- Changed isSingleNumber method behaviour. Now this flag is calculated on demand.
IntegersSubsetMapping
- Optimized diff operation.
- Replaced type of Items field from std::list with std::map.
- Added new methods:
bool isOverlapped(self &RHS)
void add(self& RHS, SuccessorClass *S)
void detachCase(self& NewMapping, SuccessorClass *Succ)
void removeCase(SuccessorClass *Succ)
SuccessorClass *findSuccessor(const IntTy& Val)
const IntTy* getCaseSingleNumber(SuccessorClass *Succ)
IntegersSubsetTest
- DiffTest: Added checks for successors.
SimplifyCFG
Updated SwitchInst usage (now it is case-ragnes compatible) for
- SimplifyEqualityComparisonWithOnlyPredecessor
- FoldValueComparisonIntoPredecessors

same time perform up to three operations:
- LHS exclude RHS
- LHS intersect RHS (LHS successors will keeped)
- RHS exclude LHS
The complexity is N+M, where
N is size of LHS
M is size of RHS.

Changed type of Items collection: from std::vector to std::list.
Also some small fixes made in IntegersSubset.h, IntegersSubsetMapping.h and IntegersSubsetTest.cpp.

- Fixed IntegersSubsetGeneric copy/assignment behaviour.
- Fixed IntegersSubsetGeneric::getSize/getSingleValue methods.
- Fixed IntegersSubsetGeneric::verify method.
Also IntegersSubset.h and IntegersSubsetMapping.h headers was fixed.
