Well, when I was fixing the issues with externally visible attributes, I also
decided it should go to first place when we analyze compilation unit and it is
where process_function_and_variable_attributes is called. See
cgraph_analyze_functions.
It is done just before cgraph construction and outputs other warnings too.
