c8e665431b * 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

260ab20422 Significantly rework InstructionCombining to work better and to be cleaner.
We now use an InstVisitor to delegate to different cases that we are
interested in handling.  We also fix the FIXME's by adding users to the
worklist when appropriate.

28a01b2069 * Clean up the code a bit
* Allow structs with negative offsets.  This enables the em3d benchmark to
  be made typesafe.  In this case, the struct had an array as the first
  element, so a negative index was ok (the expr was -8 + 8x)

011ab80ed6 * 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.

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

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

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.
