Update the code to call the new convolution functions to do subpixel prediction rather than the existing functions. Remove the old C and assembly code, since it is unused. This causes a 50% performance reduction on the decoder, but that will be resolved when the asm for the new functions is available. There is no consensus for whether 6-tap or 2-tap predictors will be supported in the final codec, so these filters are implemented in terms of the 8-tap code, so that quality testing of these modes can continue. Implementing the lower complexity algorithms is a simple exercise, should it be necessary. This code produces slightly better results in the EIGHTTAP_SMOOTH case, since the filter is now applied in only one direction when the subpel motion is only in one direction. Like the previous code, the filtering is skipped entirely on full-pel MVs. This combination seems to give the best quality gains, but this may be indicative of a bug in the encoder's filter selection, since the encoder could achieve the result of skipping the filtering on full-pel by selecting one of the other filters. This should be revisited. Quality gains on derf positive on almost all clips. The only clip that seemed to be hurt at all datarates was football (-0.115% PSNR average, -0.587% min). Overall averages 0.375% PSNR, 0.347% SSIM. Change-Id: I7d469716091b1d89b4b08adde5863999319d69ff
