Subject: [PATCH, i386]: Fix PR88418, ICE in extract_insn

Hello!

For vector modes we have to use vector_operand predicate, which
rejects unaligned operands for non-avx targets.

    PR target/88418
    * config/i386/i386.c (ix86_expand_sse_cmp): For vector modes,
    check operand 1 with vector_operand predicate.
    (ix86_expand_sse_movcc): For vector modes, check op_true with
    vector_operand, not nonimmediate_operand.
