TODO(JBB):  The best fix would involve removing duplicate library
functions between vp8 and vp9...

Added a skipping test in non-rd inter-mode. After interpolation
prediction step, the residuals are tested to see if they will be
quantized to 0 based on modeling between spatial domain and
frequency domain.

Set static-thresh to 800 for >=720p and 300 for <720p, rtc set
tests showed
1. Speed 5, psnr: -0.514%; ssim: -1.748%;
   speedup on related clips: 5% -11%
2. Speed 6, psbr: -0.628%; ssim: -1.637%;
   speedup on related clips: 4% - 9%

The previous approach can't scale to all of or new formats. This also
fixes YV12 input.

Because PC_TREE is encoder-level data, not MACROBLOCK-level data.
