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.

* Add support for DataStructure analysis
...
* Parameterize pass outputting with the printPass template, so analysis
output can optionally take more arguments than just a stream. The
default output mode is just to use operator<< on the analysis.
* Remove CurrentModule hack, in favor of using printPass
* Remove special operator<<'s defined for FindUsedTypes and
FindUnsafePointerTypes, in favor of printPass specializations
* Use std::cout instead of cout
