commit-bot@chromium.org be233d63ca ARM Skia NEON patches - 27 - S32A_D565_Blend 
BlitRow565: new intrinsics version of S32A_D565_Blend

This new version is basically a rewrite of the existing code with
a few speed and accuracy improvements. There is a switch to enable
pixel perfect results at the cost of a (quite big) decrease of
performances (disabled in this patch).

Here are the benchmark results (speedup vs. existing code):
