sna/gen2+: Force upload rather than perform source transformations on the CPU
If both the source and destination is on the CPU, then the thinking was
it would be quicker to operate on those on the CPU rather than copy both
to the GPU and then perform the operation. This turns out to be a false
assumption if transformation is involved -- something to be reconsidered
if pixman should ever be improved.
