ec1ff39a5f Splitted memory access methods for 32 and 64-bit code. 
The 64-bit code got >10% speedup, the 32-bit code also got about 2% because laddr cacluation optimization

8221fa6838 - Fixed zero upper 32-bit part of GPR in x86-64 mode 
- CMOV_GdEd should zero upper 32-bit part of GPR register even if the
    'cmov' condition was false !

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 ...
