backport: re PR target/80510 (Optimize Power7/power8 Altivec load/stores)

2017-06-21  Michael Meissner  <meissner@linux.vnet.ibm.com>

	Back port from mainline
	PR target/80510
	* gcc.target/powerpc/pr80510-1.c: Restrict test to 64-bit until
	32-bit support is added.  Change ITYPE size to 64-bit integer.
	* gcc.target/powerpc/pr80510-2.c: Likewise.
