code/interr: Hook internal error contexts into the saved-fp-and-pc mechanism.

  * This covers the unfortunate case of a signal handler not
having an unbroken stack frame chain to the interrupted context,
which actually occurs on threaded x86-64 FreeBSD systems.

  * Use the existing saved-fp-and-pc mechanism, used for
ALIEN-FUNCALL to cover for code compiled -fomit-frame-pointer to
treat the internal error context as an alien funcall point.
