Summary

Based on the suggestion in https://reviews.llvm.org/D62447?id=201397#inline-554867, this adds a SaturatingInst class that represents the saturating add/sub family of intrinsics. It exposes the same interface as WithOverflowInst, for this reason I have also added a common base class BinaryOpIntrinsic that holds the actual implementation code.
