2638c1136a Add RDRAND/RDSEED instructions support (+ disasm)
Of course no true random numbers will be generated - use standard "C" rand() function as stub.
In future it will be possible to improve (using another random generator) or even use real rdrand/rdseed intrinsics

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

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.
