Partial butterfly strategy is now called DCT strategy. Made changes to transform functions in preparation for optimizations.
...
-Moved fast_forward_dst and fast_inverse_dst to DCT strategies

Improve intra SAD AVX2 intrinsics.
...
- Moved implementations for different sizes to inline functions that are
defined using each other, reducing the amount of redundant code.
- Performance of sad_8bit_32x32_avx2 improved by about 10% due to unrolling of
the loop.
