Warning fixes:

        * Makefile.in (recog.o): Depend on toplev.h.
        (insn-emit.o): Depend on recog.h.
        (insn-peep.o): Depend on recog.h and insn-config.h.
        * combine.c (simplify_set): Remove unused variable `scratches'.
        * final.c (final_scan_insn): Wrap declaration of variables `vlen'
        and `idx' in macro conditional controlling their use.
        * genemit.c (main): Make the generated output file include
        recog.h.  Don't have it declare `insn_operand_constraint', since
        we get it from recog.h.
        * genpeep.c (main): Make the generated output file include
        insn-config.h and recog.h.
        * recog.c: Include toplev.h.
        (extract_insn): Remove unused variable `p'.
        * regclass.c (fix_register): Add missing braces around initializer
        for `what_option'.
        (allocate_reg_info): Move variable `i' into the scope where it is
        used.  Change its type to `size_t'.
