I don't know the new C++ ABI. I vaguely remember that rtti is now at
negative office in the vtable. In principle, jc1 should generate the
same entries at negative office. However, if they are only needed for
rtti, it may not matter that much, at least until we have integrated
Java and C++ rtti mechanisms better.
