Support integral types for kAbs in SimpleIREvaluator (#49357)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49357
This is a follow-up fix for PR #48679, where the previous PR
adds support for integer inputs to aten::abs by promoting integers to
float and then demote the result back to integers. This PR supports
integer inputs to aten::abs more efficiently in the SimpleIREvaluator
by allowing implementing integer inputs for kAbs (renamed from kFabs).
- Rename kFabs to kAbs
- Add support for integer input to kAbs in SimpleIREvalator (note that:
llvm_codegen and cuda_codegen already supports integer inputs to kAbs)
Test Plan:
- `PYTORCH_TENSOREXPR_DONT_USE_LLVM=1 python test/test_jit_fuser_te.py
TestTEFuser.test_unary_ops`
- `python test/test_jit_fuser_te.py TestTEFuser.test_unary_ops`
