[JIT] JIT should let people know we inferred an argument as a tensor (#38527)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/38527
This PR solves issue (#37200).
Error is encountered during IR generation while trying to resolve the call to sum.
Should let user know it inferred the value for argument 'dim' to be of type 'Tensor'
because it was not annotated with an explicit type.
Test Plan:
Add code to reprodue the issue (#37200)
`python test/test_jit.py TestJit.test_inferred_as_tensor`
