662a5b2370 Reorder intra4x4_pred_mode so that we can read/write 4 values at once. 
3-7 cpu cycles faster

5b0fb5244d Store intra4x4_pred_mode per row only. 
about 5 cpu cycles slower in the local code but should be overall faster
due to reduced cache use. (my sample though has too few intra4x4 blocks
for this to be meassureable easily either way)

e1c88a2138 Cut the size of mvd_table by yet another factor of 2. 
The code read/write code itself was 1 cycle faster, overall its
likely more due to cache effects

b5bd070029 Change mvd_cache & mvd_table to 8bit, this is overall a bit faster
