that take a function. Also, users should no longer
call the version of getModRefBehavior that takes
both a function and a callsite. To reduce the

Separate the call graph implementation from its interface. This implements
...
the rough idea sketched out in http://nondot.org/sabre/LLVMNotes/CallGraphClass.txt ,
allowing new spiffy implementations of the callgraph interface to be built.
Many thanks to Saem Ghani for contributing this!

(1) Bug fix that was causing nodes with dangling references to be freed.
...
We run removeDeadNodes() on the TD graph up front before using it.
(2) Major enhancement to printing of results: now we list the actual objects
that are mod/ref instead of just printing the bit vectors.
Also an important bug fix in TDDataStructures pass (no change here):
clear Mod/Ref bits of callers before inlining into a function.

to fill in

they modify (be conservative!)

modifies the underlying program)
