* Finish the implementation of isEdgeFeasible this fixes bug:

test/Regression/Transforms/SCCP/2002-05-02-EdgeFailure.ll
* SCCP now preserves the CFG: It leaves conditional branches the way they
are in the program, not simplifying them. A seperate pass should eliminate
the potentially dead basic blocks and edges in the CFG.

* Enable SCCP debugging to be turned on with a simple change of #define
...
* Change worklist to a set so that duplicates cannot happen
* 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.
* Remove obsolete comment about constant pools
