This PR makes `IO.RealWorld` opaque. It also adds a new compiler -only `lcRealWorld` constant to represent this type within the compiler. By default, an opaque type definition is treated like `lcAny`, whereas we want a more efficient representation. At the moment, this isn't a big difference, but in the future we would like to completely erase `IO.RealWorld` at runtime.
