Add improvements made in good-quality mode to real-time mode Several improvements we made in good-quality mode can be added into real-time mode to speed up encoding in speed 1, 2, and 3 with small quality loss. Tests using tulip clip showed: --rt --cpu-used=-1 (before change) PSNR: 38.028 time: 1m33.195s (after change) PSNR: 38.014 time: 1m20.851s --rt --cpu-used=-2 (before change) PSNR: 37.773 time: 0m57.650s (after change) PSNR: 37.759 time: 0m54.594s --rt --cpu-used=-3 (before change) PSNR: 37.392 time: 0m42.865s (after change) PSNR: 37.375 time: 0m41.949s Change-Id: I76ab2a38d72bc5efc91f6fe20d332c472f6510c9
