Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/24801 This is to fix the ODR-violations in fbcode static builds, which have been broken for several months. This PR is unfortunately quite large, but the changes are only mechanical: 1. Tests defined in header files -> tests defined in cpp files 2. Remove the `torch::jit::testing` namespace -> `torch::jit`. 3. Single `test.h` file that aggregates all tests. 4. Separate out files for gtest and python versions of the tests instead of using a build flag 5. Add a readme for how to add a new test, and explaining a bit about why the cpp tests are the way they are.
