450e1fbc76 Instead of using a bool that constant has to be explained, use a self
explanitory enum instead.

7d2624d4f3 Implement a new mergeInGraph method, which basically factors code out of
the BU class.

This will be used by the IPModRef class to do stuff, eventually perhaps the
TD pass will use it also.

Speaking of the TD pass, this also eliminates the self recursive case, which
was broken, and couldn't occur anyway.

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.  :)

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.

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.

c1b7de86d5 Checkin some major reworks of data structure analysis. This is not done,
nor does it work very well, but I need to get it checked in before I break
the tree unintentionally.

b9c05cf65b Use a separate globals graph to hold externally visible nodes.
This changes both the bottom-up and top-down propagation so that
globals and other external objects do not have to appear in every
function, but only in functions in which they are referenced or
they can be used to access something else that is referenced.

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.

9841c396cf Add support for a top-down propagation pass:
-- Save a copy of the original call nodes in DSGraph before inlining bottom-up.
-- Also, save a list of the callers of each function in DSGraph.
