i386.md (ix86_expand_vector_extract): Use vec_extr path for TARGET_MMX_WITH_SSE && TARGET_SSE4_1. 

* config/i386/i386.md (ix86_expand_vector_extract) <case E_V2SImode>:
	Use vec_extr path for TARGET_MMX_WITH_SSE && TARGET_SSE4_1.
	<case E_V8QImode>: Ditto.
	* config/i386/mmx.md (*mmx_pextrw_zext): Rename from mmx_pextrw.
	Use SWI48 mode iterator.  Use %k to output operand 0.
	(*mmx_pextrw): New insn pattern.
	(*mmx_pextrb): Ditto.
	(*mmx_pextrb_zext): Ditto.
