Ensure that all inter prediction goes through a common code path that takes scaling into account. Removes a bunch of duplicate 1st/2nd predictor code. Also introduces a 16x8 mode for 8x8 MVs, similar to the 8x4 trick we were doing before. This has an unexpected effect with EIGHTTAP_SMOOTH, so it's disabled in that case for now.
