* encode the result type of functions returning a zero-sized value

    using their actual type (array/record) rather than using the
    simplified type (void), so we can also return an actual value and
    assign it to something (void means that nothing is returned and
    cannot be assigned to anything) (completes fixing
    tests/test/tnoext4.pp for llvm)
