Subject: [PATCH 1/3] [OpenMP][Flang] Add "IsolatedFromAbove" and
"OutlineableOpenMPOpInterface" 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.
Related discussion: https://discourse.llvm.org/t/rfc-prevent-cse-from-removing-expressions-inside-some-non-isolatedfromabove-operation-regions/73150

Subject: [PATCH 2/3] [OpenMP][MLIR] Add "IsolatedFromAbove" and
"OutlineableOpenMPOpInterface" trait to omp.target
This patch adds the MLIR translation changes required for add the IsolatedFromAbove and OutlineableOpenMPOpInterface traits to omp.target. It links the newly added block arguments to their corresponding llvm values.

Subject: [PATCH 3/3] [OpenMP][MLIR]OMPEarlyOutliningPass removal
This patch removes the OMPEarlyOutliningPass as it is no longer required. The implicit map operand capture has now been moved to the PFT lowering stage.
