Added optimization of the 8 bit assembly quantizer routines. This makes these functions up to 100% faster, depending on encoding parameters. This patch maskes the encoder faster in both the high bitdepth and 8bit configurations. In the high bitdepth configuration, it effects profile 0 only. Based on my profiling using 1080p input the net gain is between 1-3% for the 8 bit config, and around 2.5-4.5% for the high bitdepth config, depending on target bitrate. The difference between the 8 bit and high bitdepth configurations for the same encoder run is reduced by 1% in all cases I have profiled. Change-Id: I86714a6b7364da20cd468cd784247009663a5140
