The patch is a proof of concept to create a hook to make AddressSanitizer to
handle target intrinsics for memory references.
The function getInterestingMemeoryOpereand(Intrinsic) will return an InterstingMemeoryOpereand
object of the input intrinsic. InterestingMemeoryOpereand is a data structure
to track information of memory references and used by AddressSanitizer.
