Passes all need to be initialized before they are added into a pass manager.

My idea was to create a complete backend treating Java as a normal platform, to enable LLVM to compile programs to Java Bytecode (.class) and Java Archive files (.jar). This could be useful in situations where we need to compile a program for a platform still not natively supported by LLVM. I don't know if it exists already, I've heard about this "LLJVM" but I don't think it
