Add `do yeet` expressions to allow experimentation in nightly
Using an obviously-placeholder syntax. An RFC would still be needed before this could have any chance at stabilization, and it might be removed at any point. But I'd really like to have it in nightly at least to ensure it works well with try_trait_v2, especially as we refactor the traits.
