Xfermode: SSE2 implementation of hardlight mode
With SSE2 optimization, performance of Xfermode_HardLight will improve
about 45% on desktop i7-3770. Here are the data:
before:
Xfermode_HardLight 8888: cmsecs = 48.43 565: cmsecs = 63.11
after:
Xfermode_HardLight 8888: cmsecs = 25.71 565: cmsecs = 33.46
