    Add weighted motion search for obmc predictor · 72d3ba8a
    Yue Chen authored
    Also port SIMD optimization of weighted sad/variance functions to
    av1.
    Coding gain improvement: 0.339/0.413/0.328 (lowres/midres/hdres)
    Current coding gain: 2.437/2.428/2.294
    Encoding time overhead: 17% (soccer_cif), 30% (ped_1080p25), was
    12% and 18% without motion search
