7650b94c75 * Remove the concept of a critical shadow node

212be2e569 * Eliminate ArgDSNode's completely, now rely on scalar map 
* 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.

0b7c85c06a Unify the destruction code used for node pairs vs normal nodes. This was 
causing a problem before because global values with incoming edges didn't
copy the incoming edges to the node they were being merged from, causing
the poolalloc pass to die.

1120c8b34a Many changes 
* 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

  implemented.
