NamedFlowCollection should be a ContextDestructionObserver
https://bugs.webkit.org/show_bug.cgi?id=99239

Patch by Hanyee Kim <choco@company100.net> on 2013-02-07
Reviewed by Adam Barth

This patch removes the raw pointer of Document in NamedFlowCollection.
It could be replaced with ContextDestructionObserver.
ContextDestructionObserver has the pointer and clears the pointer
automatically when the document is destroyed.
