Optimize RDMult
This commit introduces the optimized RDMult values for both key
and non-key frames. For key frames, the commit gets values back
from commit#b13f6154df9c0834d74f7e3d41e41c4208f56d18. For impact
on key frame only encodings, see commit message for that commit.
For inter frames, the values get optimzied by running encoding tests
in Q mode with the following range using 150 frames:
2 6 10 14 18 22 26 30 34 38 42 46 50 54 58 62
The impact of current set of RDMULT values:
PSNR SSIM PSNR-HVS
lowres: -0.325% 0.422% -0.228%
midres: -0.377% 0.158% -0.376%
hdres: -0.309% 0.522% -0.322%
Test baseline is on commit#35617458
Overall, the values help PSNR based metrics, but hurt SSIM metric
slightly.
