I don't plan to add any more [[nodiscard]] attributes for now, but
these two commits should demonstrate how to do it for anybody who
wants to contribute similar patches.

I didn't add tests that verify we do actually warn on each of those
functions, because there are hundreds of them, and I know they're
working because I had to alter existing tests to not warn.
