D22082806 (1e03d603c6) broke the model generation of pyper models. We trace the namedtuple as input. To unblock the development of PyPer project, let's revert the diff first.

1e03d603c6 [JIT] Infer NamedTuple type attributes of nn.Modules correctly (#39116)
Summary:
**Summary**
This commit modifies type inference for `nn.Module` instance attributes
such that the type of a `NamedTuple` attribute is inferred correctly and
such that the field names of this `NamedTuple` instance can be used in
scripted methods. At present, the type of this attribute is inferred to be
`Tuple[T, U, ..., V]`, so the field must be referred to by index and
cannot be referred to by name.

**Test Plan**
This commit adds a unit test to test that a field of a `NamedTuple`
attribute can be referred to by name in a scripted method.

**Fixes**
This commit fixes https://github.com/pytorch/pytorch/issues/37668.

c068233300 Add CHECK-SOURCE-HIGHLIGHTED to file check utils. (#39692)
Summary:
Enhance FileCheck util to check for highlighted source ranges. This is useful when writing tests regarding generated error messages that require source code highlighting.

Here is how the error looks like in different cases:

- In case of needed source code token not found at all in input string:
```
RuntimeError: Expected to find "invalid_token" but did not find it
Searched string:

...  <--- HERE
def to_list_missing_type_annotation(x):
    # type: (torch.Tensor) -> List[float]
From CHECK-SOURCE-HIGHLIGHTED: invalid_token
```

- In case of source code token not highlighted:
```
Traceback (most recent call last):
  File "test_range.py", line 11, in <module>
    FileCheck().check_source_highlighted("x.tolist()").run(s)
RuntimeError: Expected to find "~~~~~~~~~~" but did not find it
Searched string:
    # type: (torch.Tensor) -> List[float]
    li = x.tolist()
         ~~~~~~~~~ <--- HERE
         ~~~~~~~~~~~~~~~~~~~...  <--- HERE
    return li
```

It is a bit confusing since both input text (usually an error message) and generated error messages have their highlighted portions, but this is consistent of previous behavior. Another option is to generate plain error messages without additional range highlighting on input text.

c22bbb2124 [JIT] Add Type::repr_str to return human-readable str (#39544)
Summary:
Clearly expressing a type is inferred by PyTorch instead of explicitly annotated by user makes many error messages more user-friendly

Currently Type has two string conversion methods. str() for IR printing and python_str() for serialization and error message generation. If we want to include more information in type printing while maintaining serialization/deserialization correctness, we need to split python_str() into annotation_str() and repr_str().

annotation_str is solely responsible for serialization, it strictly matches format of python type annotation. repr_str() is responsible for generating a human-readable error message that includes information like "this type is inferred, not explicitly annotated"

Python class LiteScriptModule contains preliminary functions including forward, run_method and __call__.

Create a python api "load_for_lite_interpreter" under torch.jit.mobile where takes pre-saved mobile module in a file-like object as input and returns python class LiteScriptModule.

Add a python binding method "_save_to_buffer_for_mobile" under ScriptModule, and python method "_save_to_buffer_for_lite_interpreter" under RecursiveScriptModule which saves mobile module into buffer instead of file.

f90dc741eb [JIT] Normalize op aliases (#38735)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/38735

Follow up to my comment https://github.com/pytorch/pytorch/pull/36597/#issuecomment-613674329

This adds a pass to convert op aliases into a normalized form. Having two ops generated in our IR that do the same thing makes the IR harder for downstream consumers of the IR, such as TorchScript passes but also ONNX, glow, etc.

Another solution would have been to fix our code generation to only emit `aten::abs` from the start. This seems trickier, and doesn't really buy us much if we still have to expose `aten::absolute` in C++, as glaringlee of the C++ API thinks we should.

Bike shedding: maybe this should be `CanonicalizeOps` instead

6fa76b8a0c [jit] __deepcopy__ for RecursiveScriptModule (#32684)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/32684

Previously we have `clone` and `clone_instance`, where `clone` will clone both type
and value, and `clone_instance` only clone the value, both of them are shallow copies.
We need to re-evaluate whether we should expose them as a user facing API.
I think we should hide `clone`, but `clone_instance` might be useful as well, especially
when we are copying a model with very large weights, people might just want to do shallow copy.

This PR adds a `deepcopy` that might be useful as a user API, which deep copies the values, including
Tensor, but we didn't deepcopy `Blob`, `Capsule`, `Future` or `PyObject`.
For more discussions please see the following issue.

866d9d4e6a [jit] Fix name collision on load (#35720)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/35720

When modules are saved, all relevant types are serialized according to
their qualified name with a compilation unit. Since qualified names are
guaranteed to be unique within a compilation unit, this normally works
fine.

On load, all types are registered in a compilation unit owned by the
script::Module. Type names are not unique across compilation units, so
if you load two modules with colliding type names, make them submodules
of yet another module, and save that module, there is the potential of a
name collision. See the added tests for examples if that description is
confusing.

The solution is to unique type names when serializing code by mangling
them if we detect a name collision.

c235be42dd [jit] kill script namespace (#34515)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/34515

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.

2f6ffe8c39 [jit] Resolve type annotation names to types (#29623)
Summary:
This adds some machinery so that we use Python to resolve types to a value and the corresponding resolution logic in `annotations.py` instead of using the string.

This PR also `slowTests` a random test since it was taking > 1 min whereas all the other tests take < 10 seconds.

Fixes #31864
Fixes #31950
