Fix -Wdeprecated-copy in V8.

TNode has a templated constructor from TNode<U>, but this doesn't take
precedence over the auto-generated copy constructor, which results in a
warning being fired.  Fix by adding an explicit copy constructor that
does what the templated constructor does, which in turn requires fixing
some missing #includes that slipped by due to the lack of
LazyTemplateChecks() in the autogenerated copy constructor.
