396d5d7c62 Maintain enough information so that the pools for all of the nodes of 
the graph can be passed around.

f32d65d5ca Implement the first batch of transformations to the methods. So far it: 
* Converts malloc instructions to poolalloc
 * Converts free instructions to poolfree
 * Convert calls to call the new cloned hacked up versions

Note that this does not modify hacked up stuff yet, just the top level
function

though it's not entirely fleshed out.

  at the same time

291a1b1eb2 Correctly clone the function with the extra argument types. Now we need 
to modify the function next.

This also properly recycles functions so that we don't get exponential
code blowup in the common case.

Next step is to start hacking functions up.

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.

* Implement (but #ifdef out) the new, spiffier, method of determining

  implemented.
