If we want to support VEX-encoded instructions (AVX, F16C, etc.) without a ridiculous slowdown, we need to make sure we're running either all VEX-encoded instructions or all non-VEX-encoded instructions. That means we cannot mix arbitrary user-defined SkRasterPipeline::Fn (never VEX) with those living in SkOpts (maybe VEX)... it's SkOpts or bust. This ports the existing user-defined SkRasterPipeline::Fn use cases over to use stock stages from SkOpts. I rewrote the unit test to use stock stages, and moved the SkXfermode implementations to SkOpts. The code deleted for SkArithmeticMode_scalar should already be dead.
