198be22cec - Add "ResolvingCaller" to the CallSite record. This keeps track of which 
function was finally able to resolve the function call.  Adding this allows
    the TD pass to actually work right!
  - Temporarily disable dead node pruning.  This will be reenabled soon.

99a22847ba As it turns out, we don't need a fully generic mapping copy ctor, we just need 
something that maps through a std::map.  Since this simplified the client and
implementation code, do so now.

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.

3c579faece Added a first-class representation for each call site that can be 
used in the DS graphs in DSGraph.h.  With that, the special-purpose
class BUDataStructure::CallSite is no longer needed here.
