  Log Message:
  -----------
  [CIR] Add initial support for virtual base classes (#155534)

This adds support for declaring a class with a virtual base class and
initializing the vptr in the constructor. This does not yet handle
constructors that require a virtual table table (VTT) implicit argument.
