------- Additional Comments from mitz at webkit.org
Now with self-loops in the tree. In the previous patch, pages were shared by
nodes if the child node did not have any characters mapped that its parent did
not. Now the child is merged with the parent and a self-loop is added. This
prevents duplication of the (A overlay C) page in the case of fallback lists
A->B->C and A->C where B has no mappings that A does not have.
