i386-expand.c (ix86_expand_vector_init_one_nonzero): Use vector_set path for TARGET_MMX_WITH_SSE && TARGET_SSE4_1.

	* config/i386/i386-expand.c (ix86_expand_vector_init_one_nonzero)
	<case E_V8QImode>: Use vector_set path for
	TARGET_MMX_WITH_SSE && TARGET_SSE4_1.
	(ix86_expand_vector_init_one_nonzero) <case E_V8QImode>:
	Do not widen for TARGET_MMX_WITH_SSE && TARGET_SSE4_1.
