AVX2 Variance Optimization Optimizing the variance functions: vp9_variance16x16, vp9_variance32x32, vp9_variance64x64, vp9_variance32x16, vp9_variance64x32, vp9_mse16x16 by migrating to AVX2 some of the functions were optimized by processing 32 elements instead of 16. some of the functions were optimized by processing 2 loop strides of 16 elements in a single 256 bit register This optimization gives between 2.4% - 2.7% user level performance gain and 42% function level gain.
