Ivan Krasin 048155c399 UBSan: crash less often on corrupted Vtables. ...

Summary:
This CL adds a weak check for a Vtable prefix: for a well-formed
Vtable, we require the prefix to be within [-1<<20; 1<<20].

Practically, this solves most of the known cases when UBSan segfaults
without providing any useful diagnostics.
