	Eliminate the need for POP_FRAME.
	* frame.c (do_frame_unwind_register): New function.
	(frame_pop): When no POP_FRAME, pop the frame using register
	unwind and a scratch regcache.
	(frame_saved_regs_pop): Delete function.
	(trad_frame_unwinder): Update.
	* d10v-tdep.c (d10v_frame_pop): Delete function.
	(d10v_frame_unwind): Update.
	* sentinel-frame.c (sentinel_frame_pop): Delete function.
	(sentinel_frame_unwinder): Update.
	* dummy-frame.c (dummy_frame_pop): Delete function.
	(dummy_frame_unwind): Update.
	* frame-unwind.h (frame_unwind_pop_ftype): Delete definition.
	(struct frame_unwind): Update.
