LOG: [OMPIRBuilder] Avoid invalid debug location. (#153190)

Fixes #153043.

This is another case of debug location not getting updated when the
insert point is changed by the `restoreIP`. Fixed by using the wrapper
function that updates the debug location.

Added: 
    clang/test/OpenMP/amdgcn_debug_nowait.c

Modified: 
    llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp

Removed:
