Xfermode: SSE2 implementation of overlay_modeproc

With SSE2 optimization, performance of Xfermode_Overlay will improve
about 35% on desktop i7-3770. Here are the data:
before:
Xfermode_Overlay   8888:  cmsecs =     44.17   565:  cmsecs =     59.27
after:
Xfermode_Overlay   8888:  cmsecs =     28.30   565:  cmsecs =     35.84
