The speedup in rd_pick_partition() function makes it possible to drop use_lastframe_partitioning feature. By doing that, we achieve good PSNR gain with small speed loss. Also, this makes encoding loop less complicated. The code cleanup patch will follow. Borg tests showed: 1. At speed 2, stdhd set: 0.201% PSNR gain, 0.133% SSIM gain; derf set: 0.262% PSNR gain, 0.276% SSIM gain. 2. At speed 3, stdhd set: 0.139% PSNR gain, 0.109% SSIM gain; derf set: 0.447% PSNR gain, 0.442% SSIM gain. The average speed loss over selected test clips is within 1% with the worst case of 4%.
