05c7a1e61b Fixed problem with trace cache enabled 
String instructions might confise trace cache by finishing instruction execution method without actually completing an instruction (and advancing eip)

c51888f43f Split last BxLockable opcodes -> this allows to eliminate mod==0xc0 check from fetchdecode of every instruction 
reduce ACPU.CC dependencies - now that file doesn't depend of CPU

506dc3d963 Optimize 64-bit fetchdecode prefix handling 
Deparecated set_FLAG() method, setB_FLAG() method was used everywhere
Rename setB_FLAG to set_FLAG, so set_FLAG() will must receive 0/1 inly

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.
