Eric Christopher 020545d386 Temporarily Revert "[OpenMP] Add Additional Function Attribute Information to OMPKinds.def" 
as it's causing a few unused variable warnings via the macro instantiation:

sources/llvm-project/llvm/include/llvm/Frontend/OpenMP/OMPKinds.def:649:17: error: unused variable 'InaccessibleOnlyAttrs' [-Werror,-Wunused-variable]
__OMP_ATTRS_SET(InaccessibleOnlyAttrs,
                ^

This reverts commit 09fe0c5ab9.
