* recog.h (struct recog_data): Make dup_num, operand_address_p,
        n_operands, n_dups, n_alternatives `char' instead of `unsigned char'.
        (struct insn_data): Likewise with n_operands, n_dups,
        n_alternatives, output_format.
        * regclass.c (scan_one_insn): Cast n_operands to int before
        arithmetic inside comparison.
