[APX EGPR] Handle GPR16 only vector move insns

For vector move insns like vmovdqa/vmovdqu, their evex counterparts
requrire explicit suffix 64/32/16/8. The usage of these instruction
are prohibited under AVX10_1 or AVX512F, so for we select
vmovaps/vmovups for vector load/store insns that contains EGPR if
ther is no AVX512VL, and keep the original move insn selection
otherwise.

gcc/ChangeLog:

	* config/i386/i386.cc (ix86_get_ssemov): Check if egpr is used,
	adjust mnemonic for vmovduq/vmovdqa.
	* config/i386/sse.md (*<extract_type>_vinsert<shuffletype><extract_suf>_0):
	Check if egpr is used, adjust mnemonic for vmovdqu/vmovdqa.
	(avx_vec_concat<mode>): Likewise, and separate alternative 0 to
	avx_noavx512f.
