* Fold call nodes that are indistinguishable for each other. This is a big
win for external functions like sqrt, which would multiply dramatically
before.
* Global nodes with no edges to or from them are now eliminated from the graph.

* Simplify a lot of the inlining stuff. There are still problems, but not
many
* Break up the Function representation to have a vector for every different
node type so it is fast to find nodes of a particular flavor.
* Do more intelligent merging of call values
* Allow elimination of unreachable shadow and allocation nodes
* Generalize indistinguishability testing to allow merging of identical calls.
* Increase shadow node merging power
