* ada-lang.c (ada_evaluate_subexp): Modify the value returned

        when noside is EVAL_AVOID_SIDE_EFFECTS to be an lval_memory.
        This is needed to make sure that any other treatment applied
        to the resulting value does not fail for spurious reason,
        such as trying to take the address of this value.
