Fix incorrect hash equality operator bug in Memoize In v14, because we don't have a field in RestrictInfo to cache both the left and right type's hash equality operator, we just restrict the scope of Memoize to only when the left and right types of a RestrictInfo are the same.
In master we add another field to RestrictInfo and cache both hash equality operators.
