Tile based adaptive mode search in RD loop
Make the spatially adaptive mode search in rate-distortion
optimization loop inter tile independent. Experiments suggest that
this does not significantly change the coding staticstics.
Single tile, speed 3:
pedestrian_area 1080p 1500 kbps
59192 b/f, 40.611 dB, 101689 ms
blue_sky 1080p 1500 kbps
58505 b/f, 36.347 dB, 62458 ms
mobile_cal 720p 1000 kbps
13335 b/f, 35.646 dB, 45655 ms
as compared to 4 column tiles, speed 3:
pedestrian_area 1080p 1500 kbps
59329 b/f, 40.597 dB, 101917 ms
blue_sky 1080p 1500 kbps
58712 b/f, 36.320 dB, 62693 ms
mobile_cal 720p 1000 kbps
