    This commit enables adaptive constraint on motion search range for
    smaller partitions, given the motion vectors of collocated larger
    partition as a candidate initial search point.
    
    It makes speed 0 runtime of bus at CIF and 2000 kbps goes from
    167s down to 162s (3% speed-up), at 0.01dB performance gains. In
    the settings of speed 1, this makes the runtime goes from 33687 ms
    to 32142 ms (4.5% speed-up), at 0.03dB performance gains.
    
    Compression performance wise, it gains at speed 1:
    derf  0.118%
    yt    0.237%
    hd    0.203%
    stdhd 0.438%
