* Now all and any bytes of a DSNode can be merged together individually. This
is neccesary to support the full generality of C and support aliasing
correctly.

Also, we now 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.

* 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

* 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.

Each DSGraph now keeps a list of pending callers that have not
been inlined into the function represented by that graph.
It also keeps a copy of the original call nodes before the BU pass
eliminates some of them.

* Print the globals list in the node
* Print the scalars in the scalar node
* Eliminate Scalar "label" edges in the graph
* Print fake edges lighter instead of dotted
llvm-svn: 2880
* Make the function pointer argument explicit for a call nodes
* Eliminate unreachable global values
* Merge call nodes that are identical
llvm-svn: 2266
* Fold call nodes that are indistinguishable for each other. This is a big
win for external functions like sqrt, which would multiply dramatically
before.
* Global nodes with no edges to or from them are now eliminated from the graph.
