SkRasterPipeline: memcpy-free tail code.
We don't call the tail code nearly as often as the body code, but when we do and call memcpy(), we first have to vzeroupper back into the non-AVX world. That does seem to slow things down considerably. You wouldn't think it, but this gives a nice speed up (tested on Windows).
