* Finish the implementation of isEdgeFeasible this fixes bug:

test/Regression/Transforms/SCCP/2002-05-02-EdgeFailure.ll

are in the program, not simplifying them. A seperate pass should eliminate
the potentially dead basic blocks and edges in the CFG.

* Add support for the invoke instruction
* Avoid marking store and free instructions as overdefined, since they
cannot produce a value anyway.
* Inline the OperandChangedState implementation
* Add isEdgeFeasible in preparation to fix a bug. Right now it behaves
exactly as before.

* Rename MethodPass class to FunctionPass

- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
- Method is now const
- It now takes one AnalysisUsage object to fill in instead of 3 vectors
to fill in
- Pass's now specify which other passes they _preserve_ not which ones
they modify (be conservative!)
- A pass can specify that it preserves all analyses (because it never
modifies the underlying program)
