[PATCH] D14731: [libcxx] Add clang thread safety annotations to mutex and lock_guard

[Eric Fiselier via cfe-commits]

EricWF added a comment.

So I fixed up LIT so that it also adds "-Werror=thread-safety" for both ".pass.cpp" and ".fail.cpp" tests. Could you apply it to your patch?

----------------
Does `capability` have a alternative keyword that's a reserved name? ie `__capability__`? If so we should use that instead.
