    This commit allows the encoder to check the above and left neighbor
    blocks' reference frames and motion vectors. If they are all
    consistent, skip checking the NEARMV and ZEROMV modes. This is
    enabled in speed 3. The coding performance is improved:
    
    pedestrian area 1080p at 2000 kbps,
    from  74773 b/f, 41.101 dB, 198064 ms
    to    74795 b/f, 41.099 dB, 193078 ms
    
    park joy 1080p at 15000 kbps,
    from 290727 b/f, 30.640 dB, 609113 ms
    to   290558 b/f, 30.630 dB, 592815 ms
    
    Overall compression performance of speed 3 is changed
