commit 0e554b18fe2a60f2a384d0dc86154b69bb7bc1b7
Author: Frank Barchard <fbarchard@google.com>
Date: Wed Feb 10 19:13:41 2016

port NV12ToRGB565Row_AVX2 to gcc

NV12ToRGB565Row for Intel is implemented as a 2 step conversion:
NV12ToARGBRow_SSSE3 and ARGBToRGB565Row_SSE2

NV12ToARGBRow has an AVX2 version, so this CL implements
NV12ToRGB565Row_AVX2 with call to NV12ToARGBRow_AVX2 and
ARGBToRGB565Row_SSE2.
