d10v, AVR, and soon ARM all include this check as a silent stop
condition rather than an error... perhaps that has some significance.
I know it's hit at least on ARM. I'd have to dumb down the prologue
analyzer if I wanted it not to be, or else figure out where an
inside_entry_func check has gone completely missing in the new frame
code. Just putting it unwind_this_id didn't work (don't remember why
not).
