Turn the X86 emitter into a class, so the code pointer is no longer a global, yay! Created XCodeBlock that derives from XEmitter, and the Jit now derives from XCodeBlock so it can call all ADD SUB JNZ etc without having to prefix them with "emit.". I think someone's gonna like this.

There's some cleanup still to be done, but hey, it works. There shouldn't be a noticable speed difference.

I hope GCC doesn't have a problem with the "member function pointers" I used.
