Use unsigned int128 intrinsic when available. It generates better branchless code.

d8397d367e88163e5e8a47f379c716352dc91d03 by Greg Falcon <gfalcon@google.com>:

Add absl::Hash support for Cord.  The hash function is heterogeneous with other string types: a Cord and a string with the same byte sequence will hash to the same value.

SwissTable types know about Cord, and will allow heterogeneous lookup (e.g., you can pass a Cord to flat_hash_map<string, T>::find(), and vice versa.)

Add a missing dependency to the cmake Cord target.
