[PATCH] Verifier: Don't reject varargs callee cleanup functions

[Nick Lewycky]

Hunh. I'd think I'd prefer it if the verifier could check that the function defined callee cleanup and variadic doesn't return (unless the return is a musttail). I dislike making musttail even more special, but I think I just have to learn to deal with it.
