port ARGB to 565 dithering SSE2 code to GCC.
Previously the assembly code was only available to Windows. This CL ports the SSE2 code to GCC syntax. When running a profiler on all the unittests, this function was the slowest of all functions that still ran in C code. 3.71% libyuv_unittest libyuv_unittest [.] ARGBToRGB565DitherRow_C Was ARGBToRGB565Dither_Opt (2894 ms) Now ARGBToRGB565Dither_Opt (432 ms) TBR=harryjin@google.com BUG=libyuv:492 Review URL: https://codereview.chromium.org/1397673002 .
