I'm missing something -- what was wrong with the changes in D80897 <https://reviews.llvm.org/D80897> ?
AMD's HIP compilation already piggy-backs on using clang's C++ wrappers, so this change will likely break them now and I'll be the first in line to revert the change.

@yaxunl -- Sam, does this change affect HIP compilation? If it does, perhaps we should keep C++-based macro definitions around.
