backport: Makefile.in (STAGESTUFF): Add *.peephole2.
Merge peephole2 from new_ia32_branch:
* Makefile.in (STAGESTUFF): Add *.peephole2.
(mostlyclean): Likewise.
(recog.o): Depend on resource.h.
* final.c (peephole): Conditionalize decl on HAVE_peephole.
(final_scan_insn): Likewise for the invocation of peephole.
* genconfig.c (main): Look for peephole and peephole2 patterns.
Emit HAVE_peephole* accordingly.
* genpeep.c (main): Conditionalize entire output on HAVE_peephole.
* flags.h (flag_peephole2): Declare.
* toplev.c: New pass peephole2. New flag -fpeephole2.
* genattrtab.c (main): Count DEFINE_PEEPHOLE2.
* gencodes.c (main): Likewise.
* genextract.c (main): Likewise.
* genoutput.c (main): Likewise.
* genemit.c (max_operand_1): Look for the max scratch operand.
(gen_rtx_scratch): New.
(gen_exp): Use it, and pass on new arg subroutine_type.
(gen_expand): Take max scratch into account.
(gen_split): Emit peephole2 functions.
(output_peephole2_scratch): New.
(main): Include hard-reg-set.h and resource.h. Handle peephole2.
* genrecog.c (routine_type): Add PEEPHOLE2.
(IS_SPLIT): New.
(make_insn_sequence): Match outer parallel for peep2. Discard
top level scratches and dups.
(add_to_sequence): New args insn_type and top. Update all callers.
Handle toplevel peep2 matching insns.
(write_subroutine): Handle peep2.
(write_tree_1): Likewise.
(write_tree): Likewise.
(main): Likewise.
(change_state): New arg afterward. Update all callers.
Handle matching separate insns.
* recog.c (recog_next_insn): New.
(peephole2_optimize): New.
* rtl.def (DEFINE_PEEPHOLE2): New.
* resource.c (find_free_register): New argument last_insn. Use it
to find a register available through the entire span.
* resource.h (find_free_register): Update prototype.
