Once upon a time we thought this was necessary. In reality it is not, so
removing it.
For backcompat, our public interface (defined in `api/`) still has
typedefs to the old `script::` names.
There was only one collision: `Pass` as a `Stmt` and `Pass` as a graph
transform. I renamed one of them.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/28129
The previous PR in the stack removed the need to order classes/functions
or have correct import statements. This resolved circular depedency issues
that can arise when class constructors like ModuleList put new instances
of themselves in a common namespace.
This PR changes our export format to no longer produce this information.
By doing so we can make the logic signficantly simpler, since we just
keep track of an individual PythonPrint object per file.
Notes:
* PythonPrint was changed to manage its own stream/list of ranges. It
was doing this anyway internally, this just makes the API more clear.
* Since we are changing the serialization format, I also removed op_version_set.
It is now replaced with the VERSION number that written in the zip archive.
This further simplifies the code emission process.
* A test of op_version_set was removed since there is no longer any behavior
to test.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/26666
Changes:
- Introduce a `ConcreteModuleType` concept. This acts both as the key into the type
cache, and as the source of truth for `ModuleValue::attr` queries. It needs
to do both jobs because that's how we ensure correctness (if the types are
different, it's because `ModuleValue::attr` would return different things).
- Now `recursive_script` will first construct a `ConcreteModuleType` and search for a
pre-existing type before starting compilation.
- All previous paths to creating a `ScriptModule` (including inheriting from
`ScriptModule`) are now rewritten to go through `create_script_module`, so
that we have only a single place where construction happens.
Behavioral changes:
- Big change to `torch.jit.ScriptModule` inheritance: all attributes are now
recursively scripted if possible, matching recursive scripting semantics.
This makes it hard to keep something from being scripted (for example, a
Python submodule). Possibly we'll need an `ignore()` type thing for
attributes. In particular, this adds `self.training` to *every* ScriptModule, since
it's present on every `nn.Module`.
- I believe this change to be transparent to existing users of the inheritance API, since if you had an attribute that is unscriptable that you never used, there is no error. In some cases, we will create new attributes (even if they are unused), which will increase serialized model size from before.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/26758
This PR changes the order in which we import classes and functions so
that is is no longer necessary for them to defined in order in a file,
or for there to be proper import statements in the exported file.
Actually importing a function/class now is driven by the need to resolve
the entity during unpickling, type resolution, or value resolution.
While this should allow significant simplification to the code that
serializes classes, this work has not been done yet in order to avoid
inevitable forward compat issues in the transition period.
Notes:
* Individual functions have been replaced with a SourceImporter object
that exposes a resolveType method. This method loads the type if
it has not been loaded yet, potentially parsing (but not loading)
the file it exists in if that file hasn't been parsed yet.
* Some legacy functionality needed to be added as a method to this object
since the old format still used some of this logic for class resolution.

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.
