Fix traced StyleResolverStats
Fix traced StyleResolverStats

In r197513[1] we changed to pass a RefPtr<TracedValue> to a TRACE_EVENT macro, but
this resulted in tracing coercion to bool. This patch reverts to using PassRefPtr
but makes which macro we use conditional on whether we have a second argument.
