Richard Smith c195c25b22 Don't speculatively emit VTTs for classes unless we are able to correctly emit references to all the functions they will (directly or indirectly) reference.
Summary:
This fixes a miscompile where we'd emit a VTT for a class that ends up
referencing an inline virtual member function that we can't actually
emit a body for (because we never instantiated it in the current TU),
which in a corner case of a corner case can lead to link errors.
