536cf1b13f * Rename MethodPass class to FunctionPass
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
* s/Method/Function/g in other random places as well

249f5243f1 * Add names to the symbol table for pool types and modified types

* Fix bug with pooldestroy call where we passed in the size of the object
  instead of the pool to destroy.  bisort is now pool allocated successfully!

3b04124abd * Add documentation
* Split the CleanGCC pass into two passes, a global pass and an IP pass.
  Before it was just a global pass, but it did illegal things to the
  module, which broke other passes that were being scheduled with it by
  gccld.

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

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

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.
