    * config/i386/sse.md (xop_pcmov_<mode>): Change operand 1 predicate
    to register_operand and operand 2 predicate to nonimmediate_operand.
    (xop_pcmov_<mode>256): Ditto.
    * config/i386/i386.c (ix86_expand_sse_movcc): When generating
    xop_pcmov, force op_true to register.  Also, force op_false to
    register if it doesn't satisfy nonimmediate_operand predicate.
