    ada: A discriminant of a variable is not a variable
    
    gcc/ada/
    
            * sem_util.adb
            (Is_Variable): Correctly return False for a selected component
            name of the form Some_Object.Some_Discriminant, even if
            Some_Object is a variable. We don't want to allow such a name as
            an actual parameter in a call if the corresponding formal
            parameter's mode is not "in".
