This is identical to the PlatformThread::Sleep() implementation for all the
platforms.  Thus, I suggest deleting this function.  Then, you can also delete
trace_event_unittest.h.

Done.

   do {
     base::PlatformThread::Sleep(base::TimeDelta::FromMilliseconds(1));
-  } while (base::TimeTicks::HighResNow() < end_time);
+  } while (base::TimeTicks::Now() < end_time);
 }
