    This commit makes ext-tx and rect-tx experiments supported in the
    cb4x4 mode. It resolves an enc/dec mismatch issue when all the
    transform experiments are enabled.
    
    The coding gains are
            ext-tx + rect-tx   cb4x4    vartx     total
    lowres      4.0%           2.3%      0.5%     6.9%
    
    The encoding speed is about the same when cb4x4 and vartx are
    further enabled.
