In Summary: 

If an element has an ID it just unconditionally calls treeScope()->registerID() from insertedIntoTree(), and treeScope()->unregisterID() from willRemove().

Nodes that are not in the Document are inserted into a new TreeScope-derived class DocumentAssociated, of which there is exactly 1 instance per Document, owned by the Document.

DocumentAssociated::registerID()/unregisterID() are no-ops.

With this, we can also get rid of all the instances where inDocument() is queried.
