* Make the function pointer argument explicit for a call nodes
* Eliminate unreachable global values
* Merge call nodes that are identical
llvm-svn: 2266
* Fold call nodes that are indistinguishable for each other. This is a big
win for external functions like sqrt, which would multiply dramatically
before.
* Global nodes with no edges to or from them are now eliminated from the graph.

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.
llvm-svn: 2079
* Implement a new form of node folding to catch cases missed in Addtree
* Add removeIndistinguishableNodePairs to merge calls (todo) and globals
llvm-svn: 2062
* 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
llvm-svn: 2010
* 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.
