Frank Barchard e58eeea369 [libyuv] Add SwapUVRow_AVX2 and NV12ToNV21 ... Add SwapUVRow_AVX2 implementation in row_win.cc for MSVC and enable HAS_SWAPUVROW_AVX2 under USE_ROW_WIN. Share kShuffleUVToVU shuffle table between SSSE3 and AVX2 in row_gcc.cc. Make NV12ToNV21 the primary implementation and alias NV21ToNV12 to it. Add NV12ToNV21 test in convert_test.cc and benchmark dispatch for SSSE3 and AVX2 in planar_test.cc.
