Our generated code does not keep the context in a special register anymore (for quite some time now). The context is just another definition in the IR language and gets assigned register locations by the linearscan register allocator. Furthermore we no longer use an empty context for closures which have no captured states, instead the context of those closures is just `null`. This CL therefore removes Object::empty_context() and the CTX constant.
