    * Calculate sx4, sy4 by truncation instead of rounding
    * Move some repeated calculations out of the filter loop
    This is expected to have a roughly neutral effect on BDRATE.
    The speedup of each filter (SSE2, lowbd SSSE3, highbd SSSE3) is
    7-10%, for a total speedup of 14-18% when considered together
    with patches f7a5ee53 and 14b8112b.
