Replace BxAnother attribute in fetchdecode by table lookup like it is done in disasm. This is done in preparation to feature huge fetchdecode change - all fethdecode tables will be duplicated and made separatate table for ModC0 and others.
...
So ALL instructions will emjoy SplitMod11b automatically (if they want).
After splitting ALL instruction I hope to get 20% speedup at least.
