Is this #if needed?

[sof, 2014/02/12 07:48:51]

Think so; one will be a Vector<RefPtr>, the other a RawPtr<>.

+    visitor->trace(m_voiceList);
+    visitor->trace(m_currentSpeechUtterance);
+#endif
+    for (Deque<RefPtrWillBeMember<SpeechSynthesisUtterance> >::const_iterator it = m_utteranceQueue.begin(); it != m_utteranceQueue.end(); ++it)
+        visitor->trace(*it);

[haraken, 2014/02/12 05:18:45]

Can't you write this like visitor->trace(m_utteranceQueue) ? If no, we should
add the trace method to Handle.h.

[sof, 2014/02/12 07:48:51]

This is over the Deque<>; should we add a trace() method for it, but not have a
WillBeHeapDeque transition type?

[haraken, 2014/02/12 08:04:50]

I think we have trace() methods for Vector<Member> and HashSet<Member>, so it
would make sense to add a trace() method for Deque<Member> as well.

On the other hand, I begin to think that it's confusing to have trace() methods
for Vector<Member>, HashSet<Member> etc, since they shouldn't be used
(basically). They should be HeapVector<Member>, HashSet<Member> etc.

[sof, 2014/02/12 10:17:09]

Sorry, I spoke incorrectly. There is a Deque<> trace(), the problem here is/was
that the Deque<> will hold RefPtrs, which we cannot automatically trace.

I've updated the code to use the Deque's trace() (iff ENABLE(OILPAN).)
