      Delete code relating to the old VP8_TUNE_SSIM flag
      as this code does not currently work and is largely made
      redundant in VP9 by the various AQ modes.

      Fix rate control bug. · 658daf36
      Paul Wilkins authored
      Fix rate control bug whereby the rate factor heuristics
      were being updated on arf overlays causing a rate surge
      for a few frames followed by a corrective drop.
      
      This fix eliminates many of the overshoot problems that
      we were seeing on hard clips (even without applying
      stricter vbr rate control) and also helps quality on
      almost all clips with some hard clips improving by >5%.
      
      Overall quality results measured at speed 2.
      Derf  +1.78% opsnr , +2.44% SSIM
      Stdhd +2.41% opsnr, +2.85% SSIM
