Looks like UBSan still needs various RTTI for some reason

After 5d7af3c38b618d438e065da9d90668e7c4baa849 "make some classes
module-private" various tests in my Linux ASan+UBSan build failed due to missing
symbols.

Identified the problematic types with

> make check screenshot gb_SUPPRESS_TESTS=x && for i in $(find instdir/program workdir/LinkTarget/CppunitTest -type f); do LD_LIBRARY_PATH=${LD_LIBRARY_PATH:+$LD_LIBRARY_PATH:}instdir/program:workdir/UnpackedTarball/cppunit/src/cppunit/.libs ldd -r "$i" 2>/dev/null | grep 'undefined symbol: _ZTI'; done

and fixed the ensuing

> sw/source/core/SwNumberTree/SwNodeNum.cxx:190:32: error: dynamic_cast from 'SwNumberTreeNode' with hidden type visibility to 'SwNodeNum' with default type visibility [loplugin:dyncastvisibility]
>             SwNodeNum* pChild( dynamic_cast<SwNodeNum*>(pNode) );
>                                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

> class SAL_DLLPUBLIC_RTTI SwNodeNum : public SwNumberTreeNode

fallout.
