We can be optimistic and try to find the symbol.
For a type named T, we can just look up the symbol "typeinfo for T".
E.g., from libstdc++
[...]
0000003be82eec80 V typeinfo for signed char
0000003be82eee60 V typeinfo for bool
0000003be82eece0 V typeinfo for char
0000003be82ee7a0 V typeinfo for double
[...]

I have an initial patch for this.
