i386: Fix and improve movhi_internal and movhf_internal some more.
An (*v,C) alternative can be added to movhi_internal to directly load
HImode constant 0 to xmm register. Also, V4SFmode moves can be used
for xmm->xmm moves instead of TImode moves when optimizing for size.
Fix invalid %vpinsrw insn template, which needs to duplicate %xmm
register for AVX targets.
Optimize GPR moves in movhf_internal in the same way as in movhi_internal.
Fix pinsrw and pextrw templates for AVX targets. Use sselog1
instead of sselog type. Also, handle TARGET_SSE_PARTIAL_REG_DEPENDENCY
and TARGET_SSE_SPLIT_REGS targets.

PR target/102811
* config/i386/i386.md (*movhi_internal): Introduce (*v,C) alternative.
Do not allocate non-GPR registers. Optimize xmm->xmm moves when
optimizing for size. Fix vpinsrw insn template.
(*movhf_internal): Fix pinsrw and pextrw insn templates for
AVX targets. Use sselog1 type instead of sselog. Optimize GPR moves.
Optimize xmm->xmm moves for TARGET_SSE_PARTIAL_REG_DEPENDENCY
and TARGET_SSE_SPLIT_REGS targets.
