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.
gcc/ChangeLog:
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.
