    Enable motion field based mode seach skip

    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 :

    Use the chessboard pattern pred search in newmv mode

    This commit extends the chessboard pattern prediction filter search.
    If the above and left blocks have the same prediction filter type,
    the encoder will skip the prediction filter type search and use the
    reference one.

    The overall chessboard pattern prediction filter type search reduces
    speed 3 runtime for hard clips. Experiments on park joy at 1080p
    and 15000 kbps show that the runtime goes from 723265 ms to 65832 ms,
    i.e., about 10% speed-up. Compression performance wise, it affects
    the coding quality by
