Detailed Description

This file defines CachedHashString and CachedHashStringRef.

These are owning and not-owning string types that store their hash in addition to their string data.

Unlike std::string, CachedHashString can be used in DenseSet/DenseMap (because, unlike std::string, CachedHashString lets us have empty and tombstone values).
