aba1ef6fc9 * Move isEquivalentTo implementations to NodeImpl 
* Implement a new form of node folding to catch cases missed in Addtree
* Add removeIndistinguishableNodePairs to merge calls (todo) and globals

f1a2a9c168 * Convert CallMap to be a vector, because the keys can change, and the map 
doesn't resort!
* Be more generous with the cached matches that we allow now.
* Recursive calls should all work now!

4c4a273f43 * Catch and ignore (for now) return instructions in tranformed functions 
* Add more debugging output
* Fix problems refering to wrong versions of various graphs
* Build the pool descriptor map!
* Clear the nodemapping map after building pool descriptor to avoid assert
* Transform the NEw function body, not the old one...
* Matrix.ll now works!

410c6394d3 * Clean up data structures [AllocDSNode -> DSNode] 
* TransformFunctionInfo now has call field form field mapping.  May be
  removed in the future.
* Moved the computation of "Scalars" into transformFunctionBody so
  transformFunction didn't have to recompute it.
* Implement the node mapping calculation in preparation to calculate
  PoolDescriptors to pass to transformFunctionBody
* Print out the node mapping [it looks right!]
* Other minor changes

the graph can be passed around.

a4b9a9f573 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

  at the same time

9166ac0b3f 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.

55186e7abf 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.
