	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.
