m32r.c: Include toplev.h.

        * m32r.c: Include toplev.h.
        (*): Add ATTRIBUTE_UNUSED as needed to arguments.
        (gen_compare): Rename swap_p to must_swap to match uses.
        Add default abort case.
        (m32r_output_function_epilogue): Remove unused variables.
        (m32r_print_operand): Use HOST_WIDE_INT_PRINT_HEX.
        * m32r.h (PROTO, STDIO_PROTO): Rename XPROTO; unconditionally
        define to empty parameter list.  Update all uses.
        (predicate decls): Use enum machine_mode not int.
        * m32r.md (movsi): Call abort, not fatal_insn.
        (zero_branch_insn, rev_zero_branch_insn): Add default abort case.
