487c7a754a3b93bc0f9de14bdced48007a96ae55 by Greg Falcon <gfalcon@google.com>:
Add support for absl::Hash to hash unordered containers. These can now be hashed directly, as well as combined in AbslHashValue implementations.
This also adds a new method, `H::combine_unordered()`, to the public AbslHashValue hash state API. This allows users to implement hash specializations for their own unordered collection types.
A traits class, `H::is_hashable<T>`, is also added to the hash state API. H::is_hashable<T>::value reflects whether type T is considered hashable by the AbslHashValue framework. This allows users to properly SFINAE templated versions of AbslHashValue. (The AbslHashValue implementation added to raw_hash_set shows an example of its use.)
