Auto merge of #54211 - nnethercote:keccak-Liveness-memory, r=nikomatsakis
Split `Liveness::users` into three. This reduces memory usage on some benchmarks because no space is wasted for padding. For a `check-clean` build of `keccak` it reduces `max-rss` by 20%. r? @nikomatsakis, but I want to do a perf run. Locally, I had these results: - instructions: slight regression - max-rss: big win on "Clean" builds - faults: big win on "Clean" and "Nll" builds - wall-time: small win on "Clean" and "Nll" builds So I want to see how a different machine compares.
