testsuite/gcc.dg/vect/pr44507.c is invalid on LP64. This:
curVal = *((unsigned long *)(&pArray[index]));
loads 8 bytes, ie. the last time around the loop this loads 4 bytes past the
end of the array. On big-endian machines this is the low 32 bits so the test
fails. The obvious fix is to replace the cast with (unsigned int *) and indeed
this makes the test pass on powerpc64.
