    Fix regression introduced by r12-5536.

    There're several failures:
    1.  unsupported instruction `pextrw` for "pextrw $0, %xmm31, 16(%rax)"
    %vpextrw should be used in output templates.
    2. ICE in get_attr_memory for movhi_internal since some alternatives
    are marked as TYPE_SSELOG.
    use TYPE_SSELOG1 instead.

    Also this patch fixs a typo and some latent bugs which are related to
    moving HImode from/to sse register w/o TARGET_AVX512FP16.

            PR target/102811
            PR target/103463
            * config/i386/i386.c (ix86_secondary_reload): Without
            TARGET_SSE4_1, General register is needed to move HImode from
            sse register to memory.
            * config/i386/sse.md (*vec_extrachf): Use %vpextrw instead of
            pextrw in output templates.
            * config/i386/i386.md (movhi_internal): Ditto, also fix typo of
            MEM_P (operands[1]) and adjust mode/prefix/type attribute for
            alternatives related to sse register.
