vector.md (vec_realign_load_<mode>): Reorder input operands to vperm for little endian. 

2013-07-24  Bill Schmidt  <wschmidt@vnet.linux.ibm.com>
	    Anton Blanchard <anton@au1.ibm.com>

	* vector.md (vec_realign_load_<mode>): Reorder input operands to
	vperm for little endian.
	* rs6000.c (rs6000_expand_builtin): Use lvsr instead of lvsl to
	create the control mask for a vperm for little endian.
