Reid Kleckner dae28732f4 Verifier: Don't reject varargs callee cleanup functions ... We've rejected these kinds of functions since r28405 in 2006 because it's impossible to lower the return of a callee cleanup varargs function. However there are lots of legal ways to leave such a function without returning, such as aborting. Today we can leave a function with a musttail call to another function with the correct prototype, and everything works out. I'm removing the verifier check declaring that a normal return from such a function is UB.
