03eac64013 Added decoding of new SSE4 instructions (recently published in Intel docs) 
At least CPUID detects them correctly
The code is never tested (still) ! (but should work fine)

9dc1790f07 Simplify and optimize fetchdecode methods. 
Now fetchdecode is simpler to understand and easier to modify, for example to support 3-byte opcodes (SSE4)

b9dedc8412 Added missed file from prev commit (waiting for moderator approval, message is too big) 
Summary changes:
- Fixed critical ICACHE bug from one of the recent commits
- Complete preliminary SMM implemntation, SMI still PANICs but 'alwayscont' should work fine
- 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
- Disasm SSE4 instructions
- Rename PNI->SSE3 everywhere in the code

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

d6f85c12f6 NMI support inside the CPU. 
Added two functions to query NMI and SMI from Bochs debugger.
In future they could be used for generating NMI or SMI by user request using GUI button (could be implemented separatelly later and under configure-time or .bocshrc option)

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 ...

024ce249bf Define SMM mode for future implementation. 
I would like all next commits be aware of SMM mode.
It can't be implemented right now (too many questions w/o answers) but it will be done till next major release definitelly.
