db02731cbf 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.

2653d54e96 split 32-bit modermdata variable in BxInstruction_c to 4 Bit8u variables 
this way it is possible to save shifts and masking when accessing modrm fields
