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

2f3c7ff8e4 implemented SMAP (Supervisor Mode Access Protection) from [Intel Architecture Instruction Set Extensions Programming Reference] rev14
fixed enabling of ADX extensions in generic CPUID when enabled through .bochsrc

75bda1d5cd implemented SVM emulation support for Bochs (incomplete yet)
I am merging the code in order to start making shortcuts between VMX emulation and SVM emulation.
Of course SVM emulation is incomplete, completely untested and not expected to work.
But someone could already take a look one the code and give some suggestions.

Also looking for anybody with existing SVM kernels - as simple as possible - for testing.

Status:
 - exceptions intercept is not implemented yet
 - IO intercept is not implemented yet
 - MSR intercept is not implemented yet
 - virtual interrupts are not implemented yet
 - CPUID is not implemented yet

No advanced SVM featurez planned - I am implementing the very basic 'Pacifica' document from 2005 using QEMU code as reference.

9be8552b80 - Implemented VM Functions support and EPTP-Switching VM Functions
- Added VMEXIT conditions for INVPCID instruction

Now Bochs is fully aligned with latest pulished Intel's SDM rev040.

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
