    Speed up keyframe encoding with model RD · 308a6397

    model_rd_for_sb() can quickly compute an approximated RD cost. We
    use the estimated RD cost to skip running full RD for some bad
    mode candidates.
    This only affects keyframe encoding. Observed 22% encoding time
    reduction, and 0.03% compression loss.
