* frame.c (create_sentinel_frame): Set type to SENTINEL_FRAME. * dummy-frame.c (dummy_frame_this_id): Use get_frame_type, instead of frame_relative_level. * sentinel-frame.c (sentinel_frame_unwinder): Set unwinder's type to SENTINEL_FRAME. * frame.h (enum frame_type): Add SENTINEL_FRAME. * s390-tdep.c (s390_prologue_frame_unwind_cache): Delete calls to frame_relative_level.
