ARM: Integrate SkyEye faster "dyncom" interpreter.
Fixed typo (make protected member public) Added license header back in. I originally removed this because I mostly rewrote the file, but meh ARM: Fixed a type error in dyncom interpreter. ARM: Updated dyncom to use unique_ptr for internal ARM state.
