Remove the reduceApply functions they are obsolete things from the days before
we had a reasonable pass system

* Rename UnlinkUndistinguishableShadowNodes & RemoveUnreachableShadowNodes
  to reflect that they can eliminate arbitrary nodes.
* Rename the ShadowNodeEliminate.cpp file to EliminateNodes.cpp for the
  same reason

* Remove RemoveUnreachableShadowNodes & UnlinkUndistinguishableShadowNodes
  to reflect the fact that they actually operate on arbitrary nodes
* Clean up public interface of FunctionDSGraph
* add getEscapingAllocations & getNonEscapingAllocations

Ooops, I did such a great job pruning nodes, that I accidentally deleted
ALL allocation nodes... hrm... bad.

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

* Define some operators on PointerVal and PVS's
* Nodes can determine whether they are foldable with another node
* Rename NewDSNode to AllocDSNode
* The Function graph breaks up all of the node types into individual
  vectors to alloc fast access when you are looking for a particular type
  of node.  Simplifies much code.
