        Use checked casts for render tree
        https://bugs.webkit.org/show_bug.cgi?id=23522

        Next step: Add casts for all the RenderTable classes and use them everywhere.

        Also added a few uses in places that were still using static_cast.
        Also made some virtual member functions private.
        Also changed RenderTable::m_tableLayout to use OwnPtr.
