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

0e9c515439 * 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:

f57b845547 * 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)
* s/Method/Function/g in other random places as well

9e77f7e08b Make ConvertableToGEP handle cases where the user is indexing into the 
first element of a structure type.  Before this would not be handled because
getStructOffset would either stop immediately (because StopEarly was true
and Offset = 0), or blast past the level we wanted.

Now ConvertableToGEP steps down through the type one level at a time, checking
the Offset and Scale conditions at each step

25d17a5001 * Factored RemovePredecessorFromBlock into BasicBlock::removePredecessor 
* Avoid messing around with this case:
  br label %A
%A:  br label %A
* Enable optimizations that are correct now.
