d0387e7e11 Dramatically simplify internal DSNode representation, get implementation 
*FULLY OPERATIONAL* and safe.  We are now capable of completely analyzing
at LEAST the Olden benchmarks + 181.mcf

7287a8f9a8 Change the letters used to represent stack and heap allocations to "S" and "H" 
respectively.  This is to make presentation easier in the paper.

226c503f31 Stop representing scalars as explicit nodes in the graph. Now the only 
nodes in the graph are memory objects, which is very nice.  This also greatly
reduces the size and memory footprint for DSGraphs.  For example, the local
DSGraph for llu went from 65 to 13 nodes with this change.  As a side bonus,
dot seems to lay out the graphs slightly better too.  :)

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.

c02c96c3de 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.

* Print edge source labels again
     * Override node shape to be Mrecord again, instead of just record.

nor does it work very well, but I need to get it checked in before I break
the tree unintentionally.

3f47f1065b * Standardize how analysis results/passes as printed with the print() virtual 
methods
* Eliminate AnalysisID:  Now it is just a typedef for const PassInfo*
* Simplify how AnalysisID's are initialized
* Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into
  the analyses themselves.
