4dedcb2670 * Add getPrimitiveSize method
* Remove isPointerType, isMethodType, etc... methods.  Use isa<> instead
* Added specialization of isa for pointer types so that DerivedTypes.h doesn't
  have to be #included to use isa<PointerType>(..)

b9a6634466 * 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.

59f0ce2a41 * 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
