Original issue's description:
> Templatize visitor arguments for TraceTrait mark and trace methods.
> 
> This CL replaces Visitor* in TraceTrait<T>::{mark,trace} methods arguments
> to template parameter VisitorDispatcher.
> 
> This is to prepare for InlinedGlobalMarkingVisitor implementaion, so that
> those methods can also be used to dispatch
> TraceTrait<T>::mark(InlinedGlobalMarkingVisitor) in addition to the current
> TraceTrait<T>::mark(Visitor*) usage.
