* frame.c (get_prev_frame): Do not call frame_type_from_pc.  Set
	the frame's type from the unwinder.
	(get_frame_type): Map UNKNOWN_FRAME onto NORMAL_FRAME.
	(create_new_frame, legacy_get_prev_frame): When the unwinder's
	type isn't UNKNOWN_FRAME, initalize "type" from the unwinder.
	(get_frame_base_address): Use get_frame_type.
	(get_frame_locals_address, get_frame_args_address): Ditto.
	(legacy_saved_regs_unwinder): Set the type to UNKNOWN_TYPE.
	* frame.h (enum frame_type): Add UNKNOWN_FRAME.
	(struct frame_info): Add comment explaining why the frame contains
	a "type" field.
	* dummy-frame.c (dummy_frame_unwind): Set the type to DUMMY_FRAME.
	* d10v-tdep.c (d10v_frame_unwind): Set the type to NORMAL_FRAME.
	* sentinel-frame.c (sentinel_frame_unwinder): Set the type to
	NORMAL_FRAME.
	* frame-unwind.h: Include "frame.h".
	(struct frame_unwind): Add "type" field.
	* Makefile.in (frame_unwind_h): Add $(frame_h).
