AK: Add FlyString, a simple flyweight string class FlyString is a flyweight string class that wraps a RefPtr<StringImpl> known to be unique among the set of FlyStrings. The class is very unoptimized at the moment. When to use FlyString: - When you want O(1) string comparison - When you want to deduplicate a lot of identical strings When not to use FlyString: - For strings that don't need either of the above features - For strings that are likely to be unique
