Chris Lattner 62b7fd136e Change references to the Method class to be references to the Function 
class.  The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

Chris Lattner 847b6e2ee7 * 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!

Chris Lattner ca9f4d39f3 * 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

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

Chris Lattner 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

Chris Lattner 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.
