causing a problem before because global values with incoming edges didn't
copy the incoming edges to the node they were being merged from, causing
the poolalloc pass to die.

* Implement a new form of node folding to catch cases missed in Addtree
* Add removeIndistinguishableNodePairs to merge calls (todo) and globals

doesn't resort!
* Be more generous with the cached matches that we allow now.
* Recursive calls should all work now!

to reflect that they can eliminate arbitrary nodes.
* Rename the ShadowNodeEliminate.cpp file to EliminateNodes.cpp for the
same reason

* Simplify a lot of the inlining stuff. There are still problems, but not
many
* Break up the Function representation to have a vector for every different
node type so it is fast to find nodes of a particular flavor.
* Do more intelligent merging of call values
* Allow elimination of unreachable shadow and allocation nodes
* Generalize indistinguishability testing to allow merging of identical calls.
* Increase shadow node merging power

* Move removeEdgesTo to be a member of DSNode
* Implement (but #ifdef out) the new, spiffier, method of determining
shadow node equivalence. This cannot be enabled until more is
implemented.

* Implement Critical Shadow node handling
* Implement routines to determine whether an allocation node is a malloc
or alloca

llvm/Support/CFG.h
* Make pred & succ iterators for intervals global functions
* Add #includes that are now neccesary because BasicBlock.h doesn't include
InstrTypes.h anymore

Method::inst_* is now in llvm/Support/InstIterator.h
GraphTraits specializations for BasicBlock and Methods are now in llvm/Support/CFG.h

function in the one .cpp file that uses it. Use ValueSet's instead.
* Prepare to delete LiveVarSet.h & LiveVarSet.cpp
* Eliminate the ValueSet class, making all old member functions into global
templates that will eventually be moved to Support.

* applyFlowFunc DOES NOT NEED TO COPY the huge BB->BBLiveVar Map every time it is invoked!
* Big cleanups.
* Make BBLiveVar.h effectively an internal header file
* Prepare LiveVarMap.h for deletion

* Convert over to valueset interface that uses insert & erase insead of add and remove
* the -> operator really isn't that hard to use!
