Macros
#define	LLE_OPTION "loop-load-elim"
#define	DEBUG_TYPE LLE_OPTION

Functions
	STATISTIC (NumLoopLoadEliminted, "Number of loads eliminated by LLE")
static bool	doesStoreDominatesAllLatches (BasicBlock StoreBlock, Loop L, DominatorTree *DT)
	Check if the store dominates all latches, so as long as there is no intervening store this value will be loaded in the next iteration.
static bool	isLoadConditional (LoadInst Load, Loop L)
	Return true if the load is not executed on all paths in the loop.
static bool	eliminateLoadsAcrossLoops (Function &F, LoopInfo &LI, DominatorTree &DT, BlockFrequencyInfo BFI, ProfileSummaryInfo PSI, ScalarEvolution SE, AssumptionCache AC, LoopAccessInfoManager &LAIs)
