923fc05b3a Implement optimization for direct function call case. This dramatically
reduces the number of function nodes created and speeds up analysis by
about 10% overall.

41c04f730b Change DSGraph stuff to use hash_(set|map) instead of std::(set|map)

f40f0a39bd 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.

0969c50cb8 - 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.

42fd169310 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.
