Subject: [PATCH] mmx.md (*vec_extract* splitters): Simplify post-reload
 splitter preparation statements.

	* config/i386/mmx.md (*vec_extract* splitters): Simplify post-reload
	splitter preparation statements.
	* config/i386/sse.md (*vec_extract* splitters): Ditto.
	(*avx_vperm_broadcast_<mode>): Use adjust_address instead of
	adjust_address_nv.
