Oh! That scotches that idea, then. Never mind, Paul.
The "Right Fix" for that bug would be to make the unwinding more
reliable. But pre-CFI we've never really been able to unwind very

but it seems like the in_function_epilogue method is the only
practical fix, whatever qualities its actual definition might have.
