Fix frame off-by-one bug.
	* frame-unwind.h (frame_this_id_ftype): Replace
	frame_unwind_id_ftype.
	(frame_prev_register_ftype): Replace frame_unwind_reg_ftype.
	(struct frame_unwind): Replace "id" with "this_id".  Replace "reg"
	with "prev_register".
	* frame-unwind.c (frame_unwind_find_by_pc): Return
	legacy_saved_regs_unwind instead of trad_frame_unwind.  Update
	comment.
	* dummy-frame.c (cached_find_dummy_frame): Delete function.
	(dummy_frame_this_id): Replace dummy_frame_id_unwind.
	(dummy_frame_prev_register): Replace dummy_frame_register_unwind.
	(dummy_frame_unwind): Update.
	* sentinel-frame.c (sentinel_frame_prev_register): Replace
	sentinel_frame_register_unwind.
	(sentinel_frame_this_id): Replace sentinel_frame_id_unwind.
	(sentinel_frame_unwinder): Update.
	* frame.h (legacy_saved_regs_unwind): Replace trad_frame_unwind.
	(struct frame_info): Rename "unwind_cache" to "prologue_cache".
	* frame.c (create_sentinel_frame): Update. Initialize
	"prologue_cache" instead of "unwind_cache".
	(frame_register_unwind): Call this frame's prev_register with the
	next frame and this frame's prologue cache.
	(get_prev_frame): Simplify.  Always call prev frame's this_id with
	this frame and prev frame's prologue cache.  Document that this
	call is shifted one to the left when compared to the
	frame_register_unwind call.
	(legacy_saved_regs_prev_register): Replace
	frame_saved_regs_register_unwind.
	(legacy_saved_regs_this_id): Replace frame_saved_regs_id_unwind.
	(legacy_saved_regs_unwinder): Replace trad_frame_unwinder.
	(legacy_saved_regs_unwind): Replace trad_frame_unwind.
	* d10v-tdep.c (d10v_frame_this_id): Replace d10v_frame_id_unwind.
	(d10v_frame_unwind): Update.
	(d10v_frame_prev_register): Replace d10v_frame_register_unwind.
	(d10v_frame_unwind_cache): Replace this "fi" with "next_frame".
	(saved_regs_unwinder): Replace this "frame" with "next_frame", and
	"saved_regs" with "this_saved_regs".
