(dwarf2_frame_sniffer): Update.
(dwarf2_signal_frame_this_id): New function.
(dwarf2_signal_frame_unwind): Use it.
(dwarf2_frame_base_sniffer): Use frame_unwind_address_in_block.
* frame.c (frame_func_unwind): Add this_type argument.
(get_frame_func): Update.
(frame_unwind_address_in_block): Add this_type argument and check it.
Fix a typo.
(get_frame_address_in_block): Update.
* frame.h (enum frame_type): Move higher in the file.
(frame_unwind_address_in_block, frame_func_unwind): Add enum frame_type
argument.
