2b9926fc8e All DSGraphs keep a reference to the targetdata they are created with. This is 
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.

80614ee5ef Implement optimization for direct function call case. This dramatically 
reduces the number of function nodes created and speeds up analysis by
about 10% overall.

715a3a3b5c eliminate the ability to remove global nodes from deadNodeElminate... for now. 
This slows stuff down a bit, but it should get much better before it gets any
worse.

5c3ce31e1f - Make DSCallSite not inherit from std::vector. Renamed methods slightly. 
Make copy ctor have two versions to avoid dealing with conditional template
    argument.  DSCallSite ctor now takes all arguments instead of taking one
    and being populated later.

dc9e142686 Added a first-class representation for each call site that can be 
used in the DS graphs.  Essentially, what was vector<DSNodeHandle>
before is now a DSCallSite with the same vector, plus pointers to the
CallInst and the caller Function.  The special-purpose class
BUDataStructure::CallSite is no longer needed.
