* 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.
