    ada: Fix wrong expansion of limited extension aggregate
    
    This happens when the ancestor part is itself an aggregate: in this case,
    the tag of the extension aggregate is wrongly set to that of the ancestor.
    
    gcc/ada/
    
            * exp_aggr.adb (Build_Record_Aggr_Code): In the case of an extension
            aggregate of a limited type whose ancestor part is an aggregate, do
            not skip the final code assigning the tag of the extension.
