    This commit turns on the Hadamard transform based rate distortion
    estimate for all block sizes in RTC coding mode. It conditionally
    skips the rate distortion estimation if all zero block flag is set
    on. No significant encoding speed change is observed. The
    compression performance of speed -6 is improved by 1.7% over using
    it only for block sizes of 32x32 and below.
