f8c3968d42 Changes list made after CVS service crash:
- Fixed critical bug in CPU code added with one of the prev commits
  - Disasm support for SSE4
  - Rename PNI->SSE3 everywhere in the code
  - Correctly decode, disassemble and execute 'XCHG R8, rAX' x86-64 instruction
  - Correctly decode, disassemble and execute multi-byte NOP 0F F1 opcode
  - Fixed ENTER and LEAVE instructions in x86-64 mode
  - Added ability to turn ON instruction trace, only GUI support is missed.
    Instruction trace could be enabled if Bochs was compiled with disasm
  - More changes Bit32u -> bx_phy_address
  - Complete preliminary implementation of SMM in Bochs, SMI is still PANICs but if you press 'continue' everything should work OK
  - Small code cleanup
  - Update CHANGES and user docs

7b6c2587a9 Now devices could be compiled separatelly from CPU
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...

37eb82c69c Totally remove the cosimulation code from Bochs.
The Bochs anyway even doesn't compile if cosimulation configured enabled.
But in the same time the cosimulation code only disturbs to the future development of Bochs debugger, for example adding x86-64 functionality ...
For those of you who still may want to see the cosimulation code inside I put it in patch and upload it Bochs CVS patches folder. Read comments for the patch ! ----------------------------------------------------------------------

d8ab4e3424 Fully implemented jump_far and ret_far in 64-bit mode.
Note that I am not sure about 100% correctness, I am just coding Intel specs ...
Code review and massive testing still required.

4e03c4448c Added some comment tags so that a script can pull out relevant parts
of the decoder to test it in standalone mode.  A few lines in cpu.h
  were re-arranged to make this easy, but no real lines of code were
  changed or generated.
Changed a few PANICs to INFOs after testing corresponding cases.

f06c8b6b95 EIP > CS.limit should not be a problem
Manual says that GP(0) shouldd be generated in this case ALWAYS
Fixed instructions PANIC messages to ERROR for this case
And ... do not leave PANIC messages w/o taking care that user could push CONTINUE button and program should know to continue after the PANIC code line. Mainly in rerurn instructions were several problems ...
