Subject: [PATCH 1/2] [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.

     Description of arguments:
+    - `val`: The value to copy.
     - `var_ptr`: The address of variable to copy.
-    - `var_type`: The type of the variable to copy.
+    - `var_type`: The type of the variable/value to copy.
     - `var_ptr_ptr`: Used when the variable copied is a member of a class, structure
       or derived type and refers to the originating struct.
     - `bounds`: Used when copying slices of array's, pointers or pointer members of
       objects (e.g. derived types or classes), indicates the bounds to be copied
       of the variable. When it's an array slice it is in rank order where rank 0
       is the inner-most dimension.
-    - `implicit`: indicates where the map item has been specified explicitly in a
-      map clause or captured implicitly by being used in a target region with no
-      map or other data mapping construct.
     - 'map_clauses': OpenMP map type for this map capture, for example: from, to and
       always. It's a bitfield composed of the OpenMP runtime flags stored in
       OpenMPOffloadMappingFlags.

Subject: [PATCH 2/2] [OpenMP][MLIR] Add "IsolatedFromAbove" 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.
