    [Ada] Don't check No_Wide_Characters restriction for illegal types
    
    gcc/ada/
    
            * sem_ch3.adb (Analyze_Private_Extension_Declaration): Check
            No_Wide_Characters restriction after rejecting illegal parent
            types.
            (Derived_Type_Declaration): Likewise.
            (Find_Type_Of_Subtype_Indic): Remove check for
            No_Wide_Characters restriction, which was done too early.
