    Calculate rd cost per transformed block · 78fbb106

    This commit makes the rate-distortion optimization loop evaluate
    the rd costs of regular quantization and all zero coeffs, per
    transformed block. It improves speed 1 compression performance:
    
    derf: 0.245%
    yt:   0.515%
    
    For a large partition that consists multiple transformed blocks,
    this allows more flexibility to selectively force a portion of
    them coded as all zero coeffs, as well be continued in the next
    patches.
