* 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
