    This commit enables forcing all coefficients zero per transformed
    block, when its rate-distortion cost is lower than regular coeff
    quantization.
    
    The overall performance improvement (including its parent patch on
    calculating rd cost per transformed block) at speed 1:
    derf:  0.298%
    yt:    0.452%
    hd:    0.741%
    stdhd: 0.006%
