    change to make use of more trellis quantization · 2e53e9e5

    when a subsequent frame is encoded as an alt reference frame, it is
    unlikely that any mb in current frame will be used as reference for
    future frames, so we can enable quantization optimization even when
    the RD constant is slightly rate-biased. The change has an overall
    benefit between 0.1% to 0.2% bit savings on the test sets based on
    vpxssim scores.
