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.

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.

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.

Fix potential division error in bdshemu, when the destination operand is not large enough to hold the result.

* INC/DEC do not modify the CF.
...
* 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.

Improved stack string detection heuristic: only consider registers which have been modified during emulation; registers which were provided as "input" can be ignored, as they most likely contain addresses or other data relevant to the emulated code. We are only interested in string dynamically built during our emulation.

Renamed REG_* fields to NDR_*, so that we don't conflict with _GNU_SOURCES.
