--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Already the frontend (or GENERIC expression simplification) generates

;; Function thefun (null)
;; enabled by -tree-original


{
  if (1)
    {
      thefun_called_with_nonnull_arg ();
    }
  return real_thefun (a, b);

I couldn't quickly spot who does this though...
