sse.md (vec_set<mode>_0): Use sse4_noavx isa instead of sse4 for the first alternative...

	* config/i386/sse.md (vec_set<mode>_0): Use sse4_noavx isa instead
	of sse4 for the first alternative, drop %v from the template
	and d operand modifier.  Split second alternative into one sse4_noavx
	and one avx alternative, use *x instead of *v in the former and v
	instead of *v in the latter.
	(*sse4_1_extractps): Use noavx isa instead of * for the first
	alternative, drop %v from the template.  Split second alternative into
	one noavx and one avx alternative, use *x instead of *v in the
	former and v instead of *v in the latter.
	(<vi8_sse4_1_avx2_avx512>_movntdqa): Guard the first 2 alternatives
	with noavx and the last one with avx.
	(sse4_1_phminposuw): Guard first alternative with noavx isa,
	split the second one into one noavx and one avx alternative,
	use *x and Bm in the former and x and m in the latter one.
	(<sse4_1>_ptest<mode>): Use noavx instead of * for the first two
	alternatives.
