[PATCH] D20352: Add XRay flags to Clang

[Dean Michael Berris via cfe-commits]

dberris added a comment.

It looks like I was using `hasArg` instead of `hasFlag`. The dangerous part here is that OptSpecifier has an unsigned non-explicit argument, and I suspect `bool` is being promoted to `unsigned` silently with clang/gcc.
