    PR target/49411
    * config/i386/i386.c (ix86_expand_multi_arg_builtins): If
    last_arg_constant and last argument doesn't match its predicate,
    for xop_vpermil2<mode>3 error out and for xop_rotl<mode>3
    if it is CONST_INT, mask it, otherwise expand using rotl<mode>3.
    (ix86_expand_sse_pcmpestr, ix86_expand_sse_pcmpistr): Fix
    spelling of error message.
    * config/i386/sse.md (sse4a_extrqi, sse4a_insertqi,
    vcvtps2ph, *vcvtps2ph, *vcvtps2ph_store, vcvtps2ph256): Use
    const_0_to_255_operand instead of const_int_operand.

    * config/i386/sse.md (blendbits): Remove mode attribute.
    (<sse4_1>_blend<ssemodesuffix><avxsizesuffix>): Use const_int_operand
    instead of const_0_to_<blendbits>_operand for operand 3 predicate.
    Check integer value of operand 3 in insn constraint.
