This fixes out of global array reads. The alternative solutions of checking the index or modifying the VLC tables to prevent the index going outside are each about 1-2 cpu cyclces slower per coded 4x4 block. The alternative of padding the global tables directly is more ugly and moving them to the context should benefit cache locality.
