    This commit makes operations of the superblock intra coding rate
    distortion optimization consistent with those used in the encoding
    process. Given the test prediction mode and transform size, the rd
    optimizer encodes and reconstructs each transformed block of the
    superblock consecutively, then computes the total rate-distortion
    costs accosicated with the current superblock to select the coding
    It achieves coding performance gains:
    derf 0.353%
    yt   1.111%
