This commit enables an adaptive prediction filter type selection for sub8x8 block sizes. In speed 1, it re-uses the filter type of collocated 8x8 block if it is tested in the rate-distortion optimization loop, for the sub8x8 blocks. Otherwise, it runs the normal test over all the three filter types. In speed 2, it re-uses the 8x8 block's prediction filter type, if available. Otherwise, force it to be EIGHTTAP.
