LLVM_ABI AliasResult	alias (const MemoryLocation &LocA, const MemoryLocation &LocB, AAQueryInfo &AAQI, const Instruction *CtxI)
	alias - If one of the pointers is to a global that we are tracking, and the other is some random pointer, we know there cannot be an alias, because the address of the global isn't taken.
LLVM_ABI ModRefInfo	getModRefInfo (const CallBase *Call, const MemoryLocation &Loc, AAQueryInfo &AAQI)
LLVM_ABI MemoryEffects	getMemoryEffects (const Function *F)
	getMemoryEffects - Return the behavior of the specified function if called from the specified call site.
