13feb0772a - 10% emulation speedup with handlers chaining optimization implemented. The 
feature is enabled by default when configure with --enable-all-optimizations
    option, to disable handlers chaining speedups configure with
        --disable-handlers-chaining

4a3209ae31 Increase cpu param length (exceeded with new icount variable) 
CHECK_MAX_INSTRUCTIONS is not needed for debugger anymore.
Next step: eliminate it for SMP as well and remove cpu_loop parameter.

b69f728246 Fixed internal debugger part of the bug: 
#3312237 stepN command might be not working properly
The problem still can be exists for SMP.

002c86660a reword all the CPU code in preparation for future CPU speedup implementation. 
Bochs emulation can be another 10-15% faster using technique described in paper

f2a87171c1 Fixed BX_INSTR_OPCODE callback, now its implementation closer to original definition. 
New, updated definition of the callback:

	void bx_instr_opcode(unsigned cpu, const Bit8u *opcode, unsigned len, bx_bool is32, bx_bool is64);

The  callback  is  called  each  time, when Bochs completes  to  decode  a new
instruction.  Through  this callback function Bochs could provide an opcode of
the instruction, opcode length and an execution mode (16/32/64).

Please note, that Bochs uses translation  caches so each simulated instruction
might be executed multiple times but decoded only once.
