Subject: [PATCH] [OpenMP][Flang] Add "IsolatedFromAbove" trait to omp.target
This patch adds the PFT lowering changes required for adding the IsolatedFromAbove and OutlineableOpenMPOpInterface traits to omp.target.
Key Changes:
- Add IsolatedFromAbove and OutlineableOpenMPOpInterface traits to target op in MLIR.
- Main reason for this change is to prevent CSE and other similar optimisations from crossing region boundaries for target operations. The link below has the discourse discussion surrounding this issue.
- Move implicit operand capturing to the PFT lowering stage.
- Update related tests.
