If we're honest, this is not a class at all. :-) Does it make sense to move
Trace to the TickSample class? Currently this looks very ugly (OK, it has been
ugly before, but I think we should fix this when moving things around.)

In general, when we have a static method, we should ask ourselves where the
right place for the code really is: It is probably in the classes which are
mentioned in the signature, most probably the one where the least feature envy
happens.

+  static void Trace(Isolate* isolate, TickSample* sample);

 } }  // namespace v8::internal
 
 #endif  // V8_SAMPLER_H_
