cd6a3b2f2c Refactored DSGraph.h:
* DSGraph.h   contains DSGraph
* DSNode.h    contains DSNode (soon UDSNode and MDSNode)
* DSSupport.h contains DSCallsite, DSTypeRec, and DSNodeHandler

317daff9bf This fixes all kinds of problems with array handling. There are still bugs to
be fixed, but we are getting much closer now.

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.

4410178282 - 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.

1276c50e7b 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.

2914391ab6 - 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.

32689f8214 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.
