I briefly looked at that, and while it does tend to move stuff around
compared to an unpatched compiler, the effects don't seem to be all that
bad. If we find a testcase where it's a real problem, we could do more
aggressive reordering after epilogue generation, when we no longer have
exit fallthroguh edges. So I'd like to ask for an OK here.
