Functions
static void	createEmptyFunction (Module &M)
static void	eliminateDeadCode (Function &F)
static uint64_t	getUniqueCaseValue (SmallSet< uint64_t, 4 > &CasesTaken, uint64_t MaxValue, RandomIRBuilder &IB)
	Return a case value that is not already taken to make sure we don't have two cases with same value.
