-Add a fix so that this builds on NetBSD/powerpc.  Otherwise we get
-pixman-vmx.c:2936:5: error: subscripted value is neither array nor pointer
-Also fix something which clearly must be bugs with loading
-vector registers from single 32-bit ints.
+Add a fix so that this builds without warnings on NetBSD/powerpc.
+Also do some simplification.
