(struct insn_info): Add member fixed_regs_live.
(note_add_store_info): New typedef.
(note_add_store): New function.
(emit_inc_dec_insn_before): Expect arg to be of type insn_info_t .
Use gen_add3_insn / gen_move_insn.
Check new insn for unwanted clobbers before emitting it.
(check_for_inc_dec): Rename to...
(check_for_inc_dec_1:) ... this. Return bool. Take insn_info
parameter. Changed all callers in file.
