* frame.h (deprecated_get_next_frame_hack): Declare.
	* frame.c (legacy_saved_regs_prev_register): Only require
	DEPRECATED_FRAME_INIT_SAVED_REGS when it is needed.  Assert that
	there are always saved regs.
	(deprecated_generic_get_saved_register): Do not require
	DEPRECATED_FRAME_INIT_SAVED_REGS.
	(legacy_get_prev_frame): Do not require DEPRECATED_FRAME_CHAIN,
	use frame ID unwind instead.
	(deprecated_get_next_frame_hack): New function.
