Filtering out the stacktrace so that the stacktrace on nodes when using fx.Tracer looks nicer. I just copied the filtering we have in [proxy_tensor.py](6720d23969/torch/fx/experimental/proxy_tensor.py (L1903-L1931)).
Previously the stacktrace looked like:
```
File "/data/users/angelayi/pytorch/moo.py", line 3964, in <module>

Instead of always propagating arg_kwarg_vals in _COPY_META_FIELDS, we
special-case the pattern matcher to propagate arg_kwarg_vals when
it sees triton_kernel_wrapper_functional.
The strategy is:
1) trace out the replacement graph with arg_kwarg_vals (which have accurate eager-mode metadata)
2) trace out the replacement graph with vals (which have the accurate Inductor metadata)
3) Propagate the arg_kwarg_vals from the first graph to the second.
4) Use the second graph as the replacement graph.
The strategy is this because we want to extend this to handle
auto_functionalized later up in the stack.

Record input fake tensors at time of tracing and store them in the node meta. Inductor passes have the possibility of changing strides, so it is safer to record the strides of the inputs at tracing. See, https://github.com/pytorch/pytorch/issues/137979 for more context.
We can also extend this to custom ops, and user-visible outputs. If this ends up being compilation time sensitive we can just record strides (and maybe storage offset, per @zou3519) instead of the complete fake tensor.

If node is AC region output and has a backward hook on it, we intentionally choose to save it.
This is to work around circular dependencies in Traceable FSDP2+AC.
Example:
```
out = fully_shard(utils.checkpoint(module))(x)
norm_out = layer_norm(out)
```
and there is a circular dependency:
1. In backward, grad_input of layer_norm aka. `out_grad` is actually dependent on `out`.
2. `out` depends on `out`'s backward hook created by FSDP2 (which does all-gather for `module` weights) in order to be recomputed.
3. `out`'s FSDP2 backward hook, as is the case for all eager backward hooks, depends on `out_grad` -> circular dependency with (1)!
Solution: check whether `out` has a backward hook, and if so, intentionally save `out` in forward graph outputs. With this, we can break the above circular dependency.

The goal of this PR is to avoid stack overflow when we create extremely long chains of thunks, and then evaluate them (e.g., as occurs if you sum(long list of symint)). The basic idea behind this PR is to only thunkify proxies if they're being created in places where they may or may not be used--crucially, symint operations that occur in user code we are tracing are eagerly placed into the graph, even if they may eventually be dead.
I annotated the PR with explanation of changes.

Mutations of inputs in backward are emitted manually, after joint_fn tracing.
With default partitioner logic they will be moved to "forward" graph, as this is operation on forward inputs.
To keep those mutations in backward:
- Introduce "subgraph" node key, that can be specified with contextmanager. When we do manual `copy_` in backward on forward input - we know that his is for backward - set subgraph="backward"
In partitioner:
Introducing optional argument subgraph, to filter out nodes with specified subgraph (node_subgraph) and not to add them to subgraph if node_subgraph is different.

This PR adds a new metadata, `torch_fn` which is meant to replace `source_fn_stack` as `source_fn_stack` is not entirely well defined between strict/nonstrict. Previous discussion [here](https://docs.google.com/document/d/1sPmmsmh6rZFWH03QBOe49MaXrQkP8SxoG8AOMb-pFk4/edit#heading=h.anmx9qknhvm).
`torch_fn` represents the torch function that a particular aten operator came from. For example, `torch.nn.Linear` goes down to the `torch.nn.functional.linear` at the `__torch_function__` layer, and then `aten.t/aten.addmm` in the `__torch_dispatch__` layer. So the nodes `aten.t/aten.addmm` will now have the `torch_fn` metadata containing the `torch.nn.functional.linear`.
The `torch_fn` metadata is a tuple of 2 strings: a unique identifier for each torch function call, and the actual torch function `f"{fn.__class__}.{fn.__name__}"`. The purpose of the first value is to distinguish between 2 consecutive calls to the same function. For example, if we had 2 calls to `torch.nn.Linear`, the nodes and corresponding metadata would look something like:
```
aten.t - ("linear_1", "builtin_function_or_method.linear"),
aten.addmm - ("linear_1", "builtin_function_or_method.linear"),
aten.t - ("linear_2", "builtin_function_or_method.linear"),
aten.addmm - ("linear_2", "builtin_function_or_method.linear"),
```
Higher order ops -- currently we can get the torch_fn metadata for nodes within the HOO's subgraph, but after retracing, this becomes the `(cond, higher_order_op.cond)` :( This is because `fx_traceback.set_current_meta` points to the cond node in the toplevel graph, rather than the original node in the subgraph. I think this is because `fx.Interpreter` does not go into the cond subgraphs. (will discuss with Yidi more ab this)

Currently, when we create proxies for a list's elements in wrap_fx_proxy_cls, we create them using the same source as the list's e.g. `LocalSource(inputs)` instead of `GetItemSource(LocalSource(inputs), index=i)`. This results in invalid guards when the tensors it contains becomes dynamic, and the guard system thinks the list is a tensor:
```
Malformed guard:
L['sizes'][0] == L['inputs'].size()[0]
Malformed guard:
2 <= L['inputs'].size()[0]

This is a lot of files changed! Don't panic! Here's how it works:
* Previously, we set `follow_imports = silent` for our mypy.ini configuration. Per https://mypy.readthedocs.io/en/stable/running_mypy.html#follow-imports, what this does is whenever we have an import to a module which is not listed as a file to be typechecked in mypy, we typecheck it as normal but suppress all errors that occurred in that file.
* When mypy is run inside lintrunner, the list of files is precisely the files covered by the glob in lintrunner.toml, but with files in excludes excluded.
* The top-level directive `# mypy: ignore-errors` instructs mypy to typecheck the file as normal, but ignore all errors.
* Therefore, it should be equivalent to set `follow_imports = normal`, if we put `# mypy: ignore-errors` on all files that were previously excluded from the file list.
* Having done this, we can remove the exclude list from .lintrunner.toml, since excluding a file from typechecking is baked into the files themselves.
* torch/_dynamo and torch/_inductor were previously in the exclude list, because they were covered by MYPYINDUCTOR. It is not OK to mark these as `# mypy: ignore-errors` as this will impede typechecking on the alternate configuration. So they are temporarily being checked twice, but I am suppressing the errors in these files as the configurations are not quite the same. I plan to unify the configurations so this is only a temporary state.
* There were some straggler type errors after these changes somehow, so I fixed them as needed. There weren't that many.
In the future, to start type checking a file, just remove the ignore-errors directive from the top of the file.
The codemod was done with this script authored by GPT-4:
```
import glob
exclude_patterns = [
...
]
for pattern in exclude_patterns:
for filepath in glob.glob(pattern, recursive=True):
if filepath.endswith('.py'):
with open(filepath, 'r+') as f:
content = f.read()
f.seek(0, 0)
f.write('# mypy: ignore-errors\n\n' + content)

Summary:
Fixed nn_module_stack dynamo produced by symbolic trace to align with the nn_module_stack metadata produced by dynamo. The key should be the module path, with the value being a unique name, and the type. Something like: `{'L__self___one_module': ("L['self'].one_module", <class 'torch.fx.graph_module.GraphModule.__new__.<locals>.GraphModuleImpl'>)}`
This was causing some tests to fail when using export + the old quantization flow (prepare_fx calls symbolic_trace).

To codegen deferred runtime asserts, I need to be able to convert sympy expressions back into regular Python expressions that I can put in FX graphs. This PR adds some of the machinery to do this: it adds a new sympy analysis that runs operations on all FX traceable operations that can also be run with plain Python int/float/bool/etc. It's tested by symbolic tracing through the analysis, and then testing that this traced graph gives the same result as running the Python analysis directly.

Summary:
In order to make sure that quantization_tag is preserved through second
stage export, this PR adds it as a special metadata that should be
preserved.
Since quantization in export path will work on top of pre dispatch
graph, subsequent post dispatch op decomposition, will decompose ops
that quant workflow tagged. In order to make sure that the patterns
identified by quantizer, remains identifiable, even after decompositions
are applied, we must preserve "quantization_tag".
This enables backend delegates, that quantized a model for specific
backend, to be able to identify "quantized" patterns.

A resubmit of https://github.com/pytorch/pytorch/pull/108447. Copy over the descriptions:
This is a follow-up of the discussion in https://github.com/pytorch/pytorch/pull/108356, where we want to repalce source_fn with source_fn_stack
Before this PR, for the following example:
```python
backend = EagerAndRecordGraphs()
@torch.compile(backend=backend, fullgraph=True)
def cond_f(pred, pred2, x, y):
def true_fn(pred2, x, y):
return x + y
def false_fn(pred2, x, y):
def true_fn2(x, y):
return x.sin() - y.cos()
def false_fn2(x, y):
return x.cos() - y.sin()
return control_flow.cond(pred2, true_fn2, false_fn2, (x, y))
return control_flow.cond(pred, true_fn, false_fn, (pred2, x, y))
```
The graph captured is shown below:
```python
class GraphModule(torch.nn.Module):
def forward(self, L_pred_ : torch.Tensor, L_pred2_ : torch.Tensor, L_x_ : torch.Tensor, L_y_ : torch.Tensor):
l_pred_ = L_pred_
l_pred2_ = L_pred2_
l_x_ = L_x_
l_y_ = L_y_
cond_true_1 = self.cond_true_1
cond_false_1 = self.cond_false_1
cond = torch.ops.higher_order.cond(l_pred_, cond_true_1, cond_false_1, [l_pred2_, l_x_, l_y_]); l_pred_ = cond_true_1 = cond_false_1 = l_pred2_ = l_x_ = l_y_ = None
return (cond,)
class GraphModule(torch.nn.Module):
def forward(self, l_pred2_, l_x_, l_y_):
add = l_x_ + l_y_; l_x_ = l_y_ = None
return add
class GraphModule(torch.nn.Module):
def forward(self, l_pred2_, l_x_, l_y_):
cond_true_0 = self.cond_true_0
cond_false_0 = self.cond_false_0
cond = torch.ops.higher_order.cond(l_pred2_, cond_true_0, cond_false_0, [l_x_, l_y_]); l_pred2_ = cond_true_0 = cond_false_0 = l_x_ = l_y_ = None
return cond
class GraphModule(torch.nn.Module):
def forward(self, l_x_, l_y_):
sin = l_x_.sin(); l_x_ = None
cos = l_y_.cos(); l_y_ = None
sub = sin - cos; sin = cos = None
return sub
class GraphModule(torch.nn.Module):
def forward(self, l_x_, l_y_):
cos = l_x_.cos(); l_x_ = None
sin = l_y_.sin(); l_y_ = None
sub = cos - sin; cos = sin = None
return sub
```
the source_fn for inner cond, sin, cos will be a (name, target) tuple:
```
('cond', <torch._ops.HigherOrderOperator object at xxx>)
('sin', 'sin')
('cos', 'cos')
('sub'. <built-in function sub>)
```
After this pr, the source_fn_stack will be a list of (name, target) tuple. The bottom of stack is the end of the list.
```
[('cond', <torch._ops.HigherOrderOperator object at xxx>), ('cond', <torch._ops.HigherOrderOperator object at xxx>)],
[('cond', <torch._ops.HigherOrderOperator object at xxx>), ('cond', <torch._ops.HigherOrderOperator object at xxx>), ('sin', 'sin')],
[('cond', <torch._ops.HigherOrderOperator object at xxx>), ('cond', <torch._ops.HigherOrderOperator object at xxx>), ('cos', 'cos')]
[('cond', <torch._ops.HigherOrderOperator object at xxx>), ('cond', <torch._ops.HigherOrderOperator object at xxx>), ('sub', <built-in function sub>)]
```

The way the aot autograd sequence_nr tracking works is that we run the aot export logic, the dynamo captured forward graph is run under an fx.Interpreter, which iterates through the nodes of the forward graph while setting the `current_metadata`.
Since during backward what is run doesn't correspond to any node during forward, we fallback to the global `current_metadata`. And since this global metadata is ends up being shared between runs, that leads to weirdness if we forget to reset things, e.g., depending whether this is the first test run, the printed results will be different.

Fixes#102375
Sequence_nr increments in the forward pass and decrements in the backward pass. Backward ops with the same sequence_nr as a forward op represent the backward implementation for the op. The long term goal is to make this information available to the profiler so users can observe which ops are fused by the inductor openai triton kernels.
Added a test for this feature **test/dynamo/test_aot_autograd.py::AotAutogradFallbackTests::test_aot_sequence_nr**. The test case uses **aot_export_module()** to create a joint fwd/bwd fx graph. Then it walks all the nodes in fx graph using fx_graph.graph.nodes. The seq_nr of each node is recorded in node.meta. During the fwd pass the seq_nr increments and it decrements during the bwd pass. This allows the user to map forward ops to their corresponding bwd ops which is useful for performance analysis.
Expected output from the test case.
