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.
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.
* Fixed FXSAVE64, PUSHAD and POPAD emulation - when explicit mnemonics were added for them, emulation support was not added, thus causing emulation to stop when encountering one of these.
