    ada: Fix assertion failure during analysis of instantiation of formal package
    
    It's an assertion on the name of an instance of a generic child unit and
    it needs to cope with a renaming of the unit.
    
    gcc/ada/
    
            * sem_ch12.adb (Instantiate_Formal_Package): Accept renamings of a
            generic parent that is a child unit for the abbreviated instance.
