Subject: 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.
