Turn on Sk4px xfermodes when we have NEON too.
For SSE, Sk4px is better than Sk4f is better than SkXfermodes_opts_SSE2 (where implemented).
For NEON, Sk4px is better than SkXfermodes_opts_arm_neon is better than Sk4f (where implemented).
This is a 1.6-1.9x speedup for Plus,Modulate, and Screen for NEON.
