Although we might not be able to build libc++ with Clang modules, this patch in itself is simply adding missing includes to our `src/` files. And those changes can be verified correct by inspection (I just looked at a few of them and they look like truly missing includes). So I think we should move forward with the patch, just maybe not with the follow-up.
