    This commit uses Hadamard transform based rate-distortion cost
    estimate for rtc coding mode decision. It improves the compression
    performance of speed -6 for many hard clips at lower bit-rates.
    For example, 5.5% for jimredvga, 6.7% for mmmoving, 6.1% for
    niklas720p. This will introduce extra encoding cycle costs at
    this point.
