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.

Committing the following as obvious.

	* gcc.dg/vect/pr44507.c (seeIf256ByteArrayIsConstant): Correct cast.
