Fix inter reconstruction for 8x8 blocks and enable 8x8 inter blocks again.

Browse source 
Inter reconstruction was modifying the movement in place when it shouldn't
have. This was causing issues only for the 8x8 blocks, because for larger
blocks the modified movement vector was too far away to be seen by the blocks
below it.
