Ok. So your commit message and explanation was pure and utter tripe,
and the real reason you want this is that llvm-mc is broken.

Please fix llvm-mc instead, ok? If the intent of llvm is to be
compatible with the gnu compiler tools, then it should do that. Plus
the gas behavior is clearly superior, so why not just improve the llvm
toolchain to match those improved semantics?
