* dwarf2-frame.c (dwarf2_frame_cache, dwarf2_frame_this_id)
(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.
* alpha-mdebug-tdep.c, alpha-tdep.c, amd64-tdep.c, amd64obsd-tdep.c,
arm-tdep.c, avr-tdep.c, cris-tdep.c, frv-tdep.c, h8300-tdep.c,

xstormy16-tdep.c, xtensa-tdep.c: Update calls to
frame_func_unwind and frame_unwind_address_in_block to specify
the frame type. Use frame_unwind_address_in_block instead of
frame_pc_unwind in sniffers.
* gdb.arch/i386-signal.c, gdb.arch/i386-signal.exp: New files.
