    i386: Check AX input in any_mul_highpart peepholes

    When applying peephole optimization to transform

            mov imm, %reg0
            mov %reg1, %AX_REG
            imul %reg0

    to

            mov imm, %AX_REG
            imul %reg1

    disable peephole optimization if reg1 == AX_REG.
