backport: re PR target/61431 (Powerpc tests pack01.c and p8vector-int128-2.c fail on little endian power8 systems)

	Back port from trunk
	2014-06-06  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/61431
	* config/rs6000/vsx.md (VSX_LE): Split VSX_D into 2 separate
	iterators, VSX_D that handles 64-bit types, and VSX_LE that
	handles swapping the two 64-bit double words on little endian
	systems.  Include V1TImode and optionally TImode in VSX_LE so that
	these types are properly swapped.  Change all of the insns and
	splits that do the 64-bit swaps to use VSX_LE.
	(vsx_le_perm_load_<mode>): Likewise.
	(vsx_le_perm_store_<mode>): Likewise.
	(splitters for little endian memory operations): Likewise.
	(vsx_xxpermdi2_le_<mode>): Likewise.
	(vsx_lxvd2x2_le_<mode>): Likewise.
	(vsx_stxvd2x2_le_<mode>): Likewise.
