There does not seem to be any pass that remove global variables. I think we could use one. This pass will look specifically for global variables that are not referenced and are not exported. Any decoration associated with the variable will also be removed. However, this could cause types or constants to become unreferenced. They will not be removed. Another pass will have to be called to remove those.
