    Optimize SSE2 warp filter · 1b888f2e

    Improve the speed of the warp filter itself by ~30%. This leads
    to an overall decoder speedup of 5-20%, depending on bitrate,
    for the global-motion experiment, and a small speedup for
    warped-motion.
    
    Applies a very minor change to the rounding during filter
    selection (ROUND_POWER_OF_TWO makes slightly more sense here
    than ROUND_POWER_OF_TWO_SIGNED, and is faster)
