08096172cc Multiple improvements 
- New shemu flag - SHEMU_FLAG_SIDT, set when sheu encounters a SIDT in ring0.
- Added the CET Tracked flag to SYSCLAL, SYSENTER and INT n instructions.
- Fixed Do Not Track prefix recognition for CALL and JMP in long-mode.
- Fixed MONITOR and MONITORX implicit operands - the rAX register encodes a virtual address that will be used as the monitored range. That address is subject to a 1 byte load.
- Fixed RMPADJUST and RMPUPDATE implicit operands - the rAX register encodes a virtual address, and the rCX register encodes a virtual address of the RMP updated entry.

f6050661d5 Multiple improvements in bdshemu 
Fixed an emulation bug for MOVZX and MOVSX instructions (https://github.com/bitdefender/bddisasm/issues/48)
New shellcode flag - call tot Wow32 reserved.
New shellcode flag - heaven's gate.
New shellcode flag - stack-pivot.
Moved bdshemu tests in a password protected zip file, so it doesn't trigger AV detections.

76d92e73c2 Multiple changes 
- Add support for AVX512-FP16 instructions, as per https://software.intel.com/content/www/us/en/develop/download/intel-avx512-fp16-architecture-specification.html
- Bug fix: zeroing with no masking is not supported, so return an error if we encounter such encodings
- Bug fix: ignore VEX/EVEX.W field outside 64 bit mode for some instructions
- Several other minor fixes and improvements

072f6e059b Build improvements 
Exclude string constants from build if BDDISASM_NO_FORMAT is defined.
Use extern "C" when declaring the public bddisasm/bdshemu functions.
Include wmmintrin.h for AES intrinisics when building using LLVM/clang.

Andrei Vlad LUTAS
f7bf814bbc Flag the rIP operand of conditional branches as being conditionally read/write instead of plain read/write. 
Bypass self-writes option in bdshemu - if set, bdshemu will not proceed to commit modifications made by the shellcode to itself.

f8a3011a49 Added support for AESDEC, AESDECLAST and AESIMC emulation, using compiler intrinsics - they will be used only if the SHEMU_OPT_SUPPORT_AES is set (so the integrator can properly check for AES-NI support in hardware). 
Fixed shemu option on Linux - make sure proper RIP is provided.
