    ada: Fix fallout of latest change
    
    Freeze_Static_Object needs to deal with the objects that have been created
    by Insert_Conditional_Object_Declaration.
    
    gcc/ada/ChangeLog:
    
            * freeze.adb (Freeze_Static_Object): Do not issue any error message
            for compiler-generated entities.
