Add llvm::cas::ObjectStore abstraction and InMemoryCAS as a in-memory CAS object store implementation. The ObjectStore models its objects as: * Content: An array of bytes for the data to be stored. * Refs: An array of references to other objects in the ObjectStore. And each CAS Object can be idenfied with an unqine ID/Hash. ObjectStore supports following general action: * Expected<ID> store(Content, ArrayRef<Ref>) * Expected<Ref> get(ID) It also introduces following types to interact with a CAS ObjectStore: * CASID: Hash representation for an CAS Objects with its context to help print/compare CASIDs. * ObjectRef: A light-weight ref for an object in the ObjectStore. It is implementation defined so it can be optimized for read/store/references depending on the implementation. * ObjectProxy: A proxy for the users of CAS to interact with the data inside CAS Object. It bundles a ObjectHandle and an ObjectStore instance.
