msan: Handle musttail calls
First, avoid calling setTailCall(false) on musttail calls. The funciton
prototypes should be "congruent", so the shadow layout should be exactly
the same.
Second, avoid inserting instrumentation after a musttail call to
propagate the return value shadow. We don't need to propagate the
result of a tail call, it should already be in the right place.
