Xfermode: SSE2 implementation of multiply_modeproc This patch implements basics for Xfermode SSE optimization. Based on these basics, SSE2 implementation of multiply_modeproc is provided. SSE2 implementation for other modes will come in future. With this patch performance of Xfermode_Multiply will improve about 45%. Here are the data on desktop i7-3770. before: Xfermode_Multiply 8888: cmsecs = 33.30 565: cmsecs = 45.65 after: Xfermode_Multiply 8888: cmsecs = 17.18 565: cmsecs = 24.87 BUG= Committed: http://code.google.com/p/skia/source/detail?r=14006 Committed: http://code.google.com/p/skia/source/detail?r=14050 R=mtklein@google.com, robertphillips@google.com Author: qiankun.miao@intel.com Review URL: https://codereview.chromium.org/202903004 git-svn-id: http://skia.googlecode.com/svn/trunk@14107 2bbb7eff-a529-9590-31e7-b0007b416f81
