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.
