c004e8f534 run an extra pass after a function has been transformed to eliminate
obviously duplicate loads of the pool base.

249f5243f1 * Add names to the symbol table for pool types and modified types
* Handle more complex structure so that power works almost
* 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!

24f4497fe9 Implement function rewriting to use offsets instead of pointers in programs.
This now works with treeadd at least, and perhaps other programs as well.

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.

2b011e7b50 Add new cleanup pass:
//  1. PHI nodes with multiple entries for the same predecessor.  GCC sometimes
//     generates code that looks like this:
//
//  bb7:  br bool %cond1004, label %bb8, label %bb8
//  bb8: %reg119 = phi uint [ 0, %bb7 ], [ 1, %bb7 ]
//
//     which is completely illegal LLVM code.  To compensate for this, we insert
//     an extra basic block, and convert the code to look like this:
//
//  bb7: br bool %cond1004, label %bbX, label %bb8
//  bbX: br label bb8
//  bb8: %reg119 = phi uint [ 0, %bbX ], [ 1, %bb7 ]
