Create a base class for chains that doesn't worry about LHS and RHS value chains as I want to search from stores which only have one value. BinOpChainList now holds pointers to OpChains so that we can pass, and operate upon, either type of object. I've also moved the SetMemoryLocations into the class so that it can be used even when not searching for MACs. ValueList is now also a SmallVectorSet so we can more easily search it.
