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.
