This change was necessary for several reasons: - Code is much clearer and more modular - The CPU object is now serializeable and therefore can be safed and restored - A dynamic translator from instructions to (optimized) JavaScript is planned. It would use `new Function` to create functions at runtime. Functions created this way don't have access to any scope (except for the global scope) and therefore were not have been able to modify registers, etc. This is now possible through the cpu object - Possibly, but not necessarily a speedgain can be achieved. See http://mrale.ph/blog/2012/09/23/grokking-v8-closures-for-fun.html Additionally, some code was moved around.
