b1782d0c90 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

5f3982df6c * 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.

be449bc1ef * Add #define to enabled debug messages 
* Move removeEdgesTo to be a member of DSNode
* Implement (but #ifdef out) the new, spiffier, method of determining
  shadow node equivalence.  This cannot be enabled until more is
  implemented.

f8e2d060cc * Because of optimization, the shadow nodes between arguments might get 
removed.  Check to see if they are there.
* Repeat optimizations while changing

bf03a52b3b * 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
