fd383435f0 - Initial code for bx_Instruction_c disassembler which (together with Bochs decoder) will replace Bochs disasm module someday (very soon).
The code already knows to disasm most of the opcodes with their operands.

- Split according to OSIZE opcodes RDFSBASE/WRFSBASE / RDGSBASE/WRGSBASE both for disasm and performance

- Minimize amount of opcode forms in ia_opcodes.h again.
  For example Udq means the same as Wdq but with no memory form.

ff79cbd596 Infrstructure change to support disasm of BxInstruction_c directly (without calling disasm)
The end goal will be also merging of disasm and cpu decoder to one module and remove the disasm.

Two bug fixes on the way:
TBM: fixed 64-bit TBM instructions with memory access (did 32-bit load instead of 64-bit)
BMI2: fixed operands order for PEXT/PDEP instructions
AVX2: fixed gather instruction decoding bug from decoder alias commit

97de484efb use enhanced gui debugger instead of classic wx debugger if BX_DEBUGGER_GUI == 1
The Windows version looks almost stable, but the GTK version fails in some cases.
That's why the classic wx debugger is still available if BX_DEBUGGER_GUI is set to 0.
- added function close_debug_dialog() to handle the simulation stop case in wx
- disable all the wx debugger related code if BX_DEBUGGER_GUI is set to 1
- added enhanced debugger specific init code similar to the code in sdl.cc
- include debugger related resources on Windows
- TODO: make the GTK / wxGTK case stable and remove the wx debugger

cc694377b9 Standartization of Bochs instruction handlers.
Bochs instruction emulation handlers won't refer to direct fields of instructions like MODRM.NNN or MODRM.RM anymore.
Use generic source/destination indications like SRC1, SRC2 and DST.
All handlers are modified to support new notation. In addition fetchDecode module was modified to assign sources to instructions properly.

Immediate benefits:
- Removal of several duplicated handlers (FMA3 duplicated with FMA4 is a trivial example)
- Simpler to understand fetch-decode code

Future benefits:
- Integration of disassembler into Bochs CPU module, ability to disasm bx_instruction_c instance (planned)

Huge patch. Almost all source files wre modified.

d4688e8b95 - Do not compile support for alignment check (#AC exception) by default
for CPU emulation performance reasons, the alignment check compilation
    still can be enabled using configure option --enable-alignment-check.

There is no software in the world which enable #AC exception checking, this
x86 feature is completely legacy but its emulation support costs up to 3-5%
emulation speed.

The checking for #AC exception enable still will be done, if

 CPL == 3, EFLAGS.AC = 1 and CR0.AM = 1

but the alignment check is not compiled in, the Bochs will PANIC with corresponding message.
You can press 'always continue' and ignore the PANIC, the simulation will continue as if alignment checking is not enabled.

bd4aa017fe Lazy flags improvement patch by Darek Mihocka - measured 5% speedup everywhere accross the board
The problem with Parity is it is generally referenced very rarely so the current lazy flags code is not efficient to updated Parify flag only (because it updates low 8 bits of .result value the existing Zero Flag has to be shadowed in .auxbits.
So I flipped it around, to make Parity be shadowed in auxbits.  .result now is only needed to derive Zero Flag, and both Sign and Parify are derived from .result + .auxbits (as Zero Flag is now).  For the 90% of the conditional jumps that are JZ or JNZ, this is a speedup.
Parity is now derived from 8 bits in .result and 8 bits in .auxbits, and Sign is derived from one flag in .result and 1 bit in .auxbits by XOR-ing them all together.  It makes the code sequences for SAHF and POPF simpler too.

A lot of code duplication was added for now - major cleanup will follow later.

75bda1d5cd implemented SVM emulation support for Bochs (incomplete yet)
I am merging the code in order to start making shortcuts between VMX emulation and SVM emulation.
Of course SVM emulation is incomplete, completely untested and not expected to work.
But someone could already take a look one the code and give some suggestions.

Also looking for anybody with existing SVM kernels - as simple as possible - for testing.

Status:
 - exceptions intercept is not implemented yet
 - IO intercept is not implemented yet
 - MSR intercept is not implemented yet
 - virtual interrupts are not implemented yet
 - CPUID is not implemented yet

No advanced SVM featurez planned - I am implementing the very basic 'Pacifica' document from 2005 using QEMU code as reference.

1b9f286945 - New way of CPUs scheduling in SMP mode brings up to 50% speedup to the
SMP emulation. New implementation uses dynamic CPU quantum value and takes
   full advantage of the trace cache. Each emulated processor will execute
   the whole trace before switching to the next processor.
 * It is also safe to use large (up to 16 instructions) quantum values for
   the SMP emulation now and improve performance even further.

The same merge also completely fixes SF bug :
  [3312237] stepN command might be not working properly

Handlers chaining speedups are also supported with SMP emulation now.

02e1a0f23c Merge lazy flags optimization by Darek Mihocka.
I measure slight but consistent speedup of ~1-3% for all guests.
Tested: Windows XP/7 boot 32/64 bit, various Linux live CD

dfd769a102 - Fixed compilation issue with cpu-level=5
- SYSCALL/SYSRET: SYSCALL/SYSRET instructions are not supported in legacy mode for Intel processors
- CPUID: CPUID.0x80000001.EDX[11] SYSCALL/SYSRET support should not be reported outside long64 mode if legacy mode SYSCALL/SYSRET is not supported
- Added new CPUDB entry - AMD K6-2 3D proc3essor (Chomper)

44241a1e56 - Added support for AVX and AVX2 instructions emulation, to enable configure
with --enable-avx option. When compiled in, AVX still has to be enabled
    using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.

  - Added support for Bit Manipulation Instructions (BMI) emulation. The BMI
    instructions support can be enabled using .bochsrc CPUID option.

371dc200fc Remove the 'trace' debug feature fro the main stream (which now runs with handlers chaining) and this way reduce each handler size.
Another 3% speedup on WinXP boot on top of handlers chaining + reduction of Bochs binary size by 45K.

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

#3312237 stepN command might be not working properly
The problem still can be exists for SMP.
