    Use pretty printers for struct member stubs

    PR29079 shows that pretty printers can be used for an incomplete
    type (stub), but only when printing it directly, not if it's
    part of another struct:
    ```
    (gdb) p s
    $1 =3D {pp m_i =3D 5}
    (gdb) p s2
    $2 =3D {m_s =3D <incomplete type>, m_l =3D 20}
    ```

    The reason is simply that in common_val_print the check for stubs
    is before any pretty printer is tried.
    It works if the pretty printer is tried before the stub check:
    ```
    (gdb) p s
    $1 =3D {pp m_i =3D 5}
    (gdb) p s2
    $2 =3D {m_s =3D {pp m_i =3D 10}, m_l =3D 20}
    ```
