7b80b53ab9 Ok, really it only takes me 3 times to get this right! 
Now use #if 0 instead of #ifdef 0

fe6c9eeae3 * 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.

13b52e71d8 * 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

5364d1a74a * Simplify the code by not bothering to name the folded constant 
* Do not skip the instruction immediately after a folded instruction.  This
  was causing the testcase failure:

definitions must still occur before function bodies, but the wierd keyword is
