Fix frame off-by-one bug.
* frame-unwind.h (frame_this_id_ftype): Replace
frame_unwind_id_ftype.
(frame_prev_register_ftype): Replace frame_unwind_reg_ftype.
(struct frame_unwind): Replace "id" with "this_id". Replace "reg"
with "prev_register".
* frame-unwind.c (frame_unwind_find_by_pc): Return
legacy_saved_regs_unwind instead of trad_frame_unwind. Update
comment.
* dummy-frame.c (cached_find_dummy_frame): Delete function.
(dummy_frame_this_id): Replace dummy_frame_id_unwind.
(dummy_frame_prev_register): Replace dummy_frame_register_unwind.
(dummy_frame_unwind): Update.
* sentinel-frame.c (sentinel_frame_prev_register): Replace
sentinel_frame_register_unwind.
(sentinel_frame_this_id): Replace sentinel_frame_id_unwind.
(sentinel_frame_unwinder): Update.
* frame.h (legacy_saved_regs_unwind): Replace trad_frame_unwind.
(struct frame_info): Rename "unwind_cache" to "prologue_cache".
* frame.c (create_sentinel_frame): Update. Initialize
"prologue_cache" instead of "unwind_cache".
(frame_register_unwind): Call this frame's prev_register with the
next frame and this frame's prologue cache.
(get_prev_frame): Simplify. Always call prev frame's this_id with
this frame and prev frame's prologue cache. Document that this
call is shifted one to the left when compared to the
frame_register_unwind call.
(legacy_saved_regs_prev_register): Replace
frame_saved_regs_register_unwind.
(legacy_saved_regs_this_id): Replace frame_saved_regs_id_unwind.
(legacy_saved_regs_unwinder): Replace trad_frame_unwinder.
(legacy_saved_regs_unwind): Replace trad_frame_unwind.
* d10v-tdep.c (d10v_frame_this_id): Replace d10v_frame_id_unwind.
(d10v_frame_unwind): Update.
(d10v_frame_prev_register): Replace d10v_frame_register_unwind.
(d10v_frame_unwind_cache): Replace this "fi" with "next_frame".
(saved_regs_unwinder): Replace this "frame" with "next_frame", and
"saved_regs" with "this_saved_regs".
