This makes SimplifyTerm idempotent. My hope is that this will reduce the number of times that the toplevel function needs to be called. If a term at the bottom of the graph doesn't map to itself when SimplifyTerm is run, then all the nodes above it will need to be re-created next time SimplifyTerm is called on the graph.
This patch adds an assertion function that isn't enabled.
