      Re-design quantization process · 9ac2f663
      Jingning Han authored
      This commit re-designs the quantization process for transform
      coefficient blocks of size 4x4 to 16x16. It improves compression
      performance for speed 7 by 3.85%. The SSSE3 version for the
      new quantization process is included.
      
      The average runtime of the 8x8 block quantization is reduced
      from 285 cycles -> 255 cycles, i.e., over 10% faster.
