        * config/i386/i386.md (*addqi_1_slp): Use register_operand predicate
        for operand 0.  Do not use (match_dup) to match operand 1 with
        operand 0.  Add check in insn constraint that either input operand
        matches operand 0.  Use SWI12 mode iterator to also handle
        HImode operands.
        (*and<mode>_1_slp): Ditto.
        (*<code>qi_1_slp): Ditto.
        (*sub<mode>_1_slp): Use register_operand predicate for operand 0.
