vsx.md (*p9_vecload_<mode>): Replace VSX_M mode iterator with VSX_M2. 

[gcc]

2015-01-06  Bill Schmidt  <wschmidt@linux.vnet.ibm.com>

	* config/rs6000/vsx.md (*p9_vecload_<mode>): Replace VSX_M
	mode iterator with VSX_M2.
	(*p9_vecstore_<mode>): Likewise.
	(*vsx_le_permute_<mode>): Restrict to !TARGET_P9_VECTOR.
	(*vsx_le_perm_load_<mode> for VSX_LE_128): Likewise.
	(*vsx_le_perm_store_<mode> for VSX_LE_128): Likewise.
	(define_split for VSX_LE128 stores): Likewise.
	(define_peephole2 for TImode LE swaps): Likewise.
	(define_split for VSX_LE128 post-reload stores): Likewise.
