    ada: Fix limited_with in Check_Scil; allow for <> in pp of aggregate
    
    Check_Scil failed due to not handling a type that came from a package that was
    mentioned in a limited-with clause.  Also, an aggregate with an uninitialized
    component was not being pretty-printed properly.
    
    gcc/ada/
    
            * pprint.adb (List_Name): Check for "Box_Present" when displaying
            a list, and emit "<>" if returns True.
            * sem_scil.adb (Check_SCIL_Node): Handle case when the type of a
            parameter is from a package that was mentioned in a limited with
            clause, and make no further checks, since this check routine does
            not have all the logic to check such a usage.
