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

8ac3790ab3 Added experimental support of AT&T syntax to disasm 
Fixed operand for CMPXCHG8B instruction

Feature request to somebidy who understand Bochs debugger code
  - to add Bochs debugger command which will switch between
    Intel and AT&T style for disassembler.

9d1b401512 Fixed several disassembler bugs 
Prepared for AT&T style support in Bochs disassembler
 - it already supports all AT&T style except opcode name suffixes
 - AT&T support in future will be possible to enable from bx_debugger

69c0b06955 fixes in disassembler 
split REPEAT instructions according to opsize to speedup execution
now each REPEATABLE instruction splitted to 3 different instructions, one for 16-bit operand size, one for 32-bit and one for 64-bit. Choosing of correct instruction occure in fetchdecode step.
