      Rewrite HORIZx4 and HORIZx8 in subpixel filter functions · ed22179a
      Yunqing Wang authored
      In subpixel filters, prefetched source data, unrolled loops,
      and interleaved instructions.
      
      In HORIZx4, integrated the idea in Scott's CL (commit:
      d22a504d), which was suggested by
      Erik/Tamar from Intel. Further tweaking was done to combine row 0,
      2, and row 1, 3 in registers to do more 2-row-in-1 operations until
      the last add.
      
      Test showed a ~2% decoder speedup.
