* frame.c (legacy_saved_regs_this_id): Return a null frame ID.
(get_frame_id): Allow the UNKNOWN_FRAME.
(frame_register_unwind, get_frame_type): Ditto.
* frame.c (legacy_frame_p): Check for DEPRECATED_TARGET_READ_FP_P
and DEPRECATED_FP_REGNUM. Don't assume that the lack of
unwind_dummy_id indicates a legacy frame.
