Chris Lattner bda898420b Inline indirect function calls that are only capable of calling one function

Chris Lattner 79db55028c Make data structure acurately get ALL edges, even loads of null fields of 
nodes that are not shadow nodes

This fixes em3d to be _correct_ if not optimial

Chris Lattner 071dea7362 * Remove the concept of a critical shadow node 
* Make the function pointer argument explicit for a call nodes
* Eliminate unreachable global values
* Merge call nodes that are identical

Chris Lattner 46b08cdc7c * Eliminate ArgDSNode's completely, now rely on scalar map 
* 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.

Chris Lattner 2e9fa6d101 Move FunctionArgument out of iOther.h into Argument.h and rename class to 
be 'Argument' instead of FunctionArgument.

Chris Lattner 9ba54b2f31 Call nodes are never equivalent 
Shadow nodes are never critical.

Chris Lattner f224b6b511 Critical shadow nodes no do not know their parent explictly.

Chris Lattner d45f4df2ae * Move the isEquivalentTo implementations here. They can probably be put 
someplace nicer in the file though.
* Add new dump method for debugging

Chris Lattner b1782d0c90 Many changes 
* 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

Chris Lattner d9c86c7c96 * Implement DSNode::removeAllIncomingEdges 
* Implement Critical Shadow node handling
* Implement routines to determine whether an allocation node is a malloc
  or alloca

Chris Lattner e604d8ec65 Initial checkin of Datastructure analysis. 
Has bugs, but shouldn't crash in theory.
