Alastair Robertson 03429f3da9 TypeGraph: Remove NodeTracker from the TypeGraph class
The TypeGraph class should only be responsible for storing Type nodes.
Traversing the graph and tracking which nodes have been visited should
not be included there.

Passes now take a NodeTrackerHolder as an input parameter, which
provides access to a zeroed-out NodeTracker.
