We do this for 2 reasons: 1. It's clearer when reading doesGC()'s code that these nodes will return true. 2. If things change in the future where clobberize() no longer reports these nodes as write(Heap), each node should be vetted first to make sure that it can never GC before being moved back to the doesGC() list that returns false.

This bug title is really hard to parse.
(In reply to Simon Fraser (smfr) from comment #6) > This bug title is really hard to parse. It actually mostly makes sense in JSC lingo! But I agree, kinda hard to parse.
