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.

bc15ae64dd 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  The Method class is obsolete (renamed) and all references to it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.

* Transform the NEw function body, not the old one...

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.

c2b5cb5619 Make ConvertableToGEP handle cases where the user is indexing into the 
first element of a structure type.  Before this would not be handled because
getStructOffset would either stop immediately (because StopEarly was true
and Offset = 0), or blast past the level we wanted.

Now ConvertableToGEP steps down through the type one level at a time, checking
the Offset and Scale conditions at each step

14fe793707 Fix the: test/Regression/Other/2002-03-20-LevelRaiseCrash.ll bug. It turned 
out that almost always the result of the add was the same as the GEP that
would be generated.  In this case, however, it wasn't, so bad things happened.

72367834b0 1. Fix bug test/Regression/Other/2002-03-20-LevelRaiseBadCodegen.ll 
2. Allow negative scales in ConvertableToGEP, so that this loop from
   alloc_tree in the Olden health benchmark is correctly raised:

       for (i = 3; i >= 0; i--)
         fval[i] = alloc_tree(level - 1, label*4 + i + 1, new);

   Stepping through the array backwards caused a negative scale.
