Fix bug with named tensors and (no) tracer support (#26106)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/26106
Previously, in the named tensors build, an operator is marked as
non-traceable if ANY of its overloads are named tensor overloads. This
breaks the tracer for things like torch.full (has a names= overload for
named tensor) and tensor.sum (has a Dimname overload for named tensor).
This PR fixes the problem by putting the "no tracer support" logic into
the location where the tracer attempts to construct a graph by adding a
Dimname/DimnameList argument to a node.
Test Plan:
- new test in test_jit.py to check if torch.full is traceable
- new test in test_namedtensor.py to check what happens when someone
tries to trace a function that uses named tensor APIs.
- [namedtensor ci]
