I saw some missed optimization opportunities in C10 using std::move and thought I would submit a PR to fix them. There are particularly a lot of them dealing with the symbolic operators which are used in quite a few places including in loops.

See the comment in ThreadLocal.h for context.
I used a slightly dirty preprocessor hack to minimize the number of changes.
The hope is that we'll be able to revert all of these soon.
Test Plan:
CI.
Built FB4A with gnustl and saw no references to cxa_thread_atexit
in the PyTorch libraries.

Opt into formatting on GitHub and format everything. This is a trial run before turning on formatting for more and eventually all of the codebase.

`ThreadLocalDebugInfo::get()` is a hot function. For example, it is called by `DefaultCPUAllocator::allocate()`. Most callers do not even bother to keep the returned `shared_ptr` around, proving that they have no lifetime issues currently. For the rest, it appears that the only way that the returned pointer could become invalid is if they then called a function that swapped out `ThreadLocalDebugInfo` using `ThreadLocalStateGuard`. There are very few such paths, and it doesn't look like any current callers of `ThreadLocalDebugInfo::get()` needed a `shared_ptr` at all.

`debug_info` is `thread_local` and this function is a leaf, so nobody else could free it out from under us. Regular pointer should be fine.

This changes the profiler per a discussion with ilia-cher offline that enables `disableProfiler()` event consolidation logic to be called from different threads (i.e. threads where the profiler was not explicitly enabled). This is needed to support the functionality enabled by D23638387 where we defer profiling event collection until executing an async callback that can execute on a different thread, to support RPC async function profiling.
This is done by introducing 2 flags `cleanupTLSState` and `consolidate` which controls whether we should clean up thread local settings (we don't do this when calling `disableProfiler()` on non-main threads) and whether we should consolidate all profiled events. Backwards compatiblity is ensured since both options are true by default.
Added a test in `test_misc.cpp` to test this.
