Title: Upgrade HashMap to new entry API in RFC 509 (https://github.com/rust-lang/rust/issues/19986)

TODOs/things that make me frowny face:

- Entry is still <'a, K, V> instead of <'a, O, V>
- I'm not happy about the fact that this clones the key even when it's already owned.
- With small keys (e.g. ints), taking a reference seems wasteful.
- The other maps are still outstanding.
