    ada: Further adjust freezing for expansion of contracts
    
    This further adjusts a test deciding whether to freeze an entity coming from
    an outer scope in an inner scope based on language rules, to the presence of
    the new internal subprogram generated because of post-conditions.
    
    gcc/ada/
    
            * freeze.adb (Freeze_Entity): For the purpose of deciding whether to
            freeze an entity coming from an outer scope in an inner scope, treat
            the internal subprogram generated because of post-conditions as also
            coming from source if the original subprogram itself does.
