* Significantly improve DEBUG output
* Aggressively fold calls together if we inlined a graph that provides
call nodes.
* Add a bailout if the current graph has over 200 call nodes in it, this is
a really whacky case that should never happen.

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.

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. :)

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.

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.

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.

* BUClosure doesn't have to worry about global nodes
* TDClosure now works with global nodes
* Reenable DNE on TD pass, now that globals work right

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.

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.

* Add new RegisterOpt/RegisterAnalysis templates for registering passes that
are to show up in opt or analyze
* Register Analyses now
* Change optimizations to use RegisterOpt instead of RegisterPass
* Add support for different "PassType's"
* Add new RegisterOpt/RegisterAnalysis templates for registering passes that
are to show up in opt or analyze
* Register Analyses now
* Change optimizations to use RegisterOpt instead of RegisterPass
* Remove getPassName implementations from various subclasses

-- 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.
