bors 508e0584e3 Auto merge of #96376 - scottmcm:do-yeet, r=oli-obk 
Add `do yeet` expressions to allow experimentation in nightly

Two main goals for this:
- Ensure that trait restructuring in https://github.com/rust-lang/rust/issues/84277#issuecomment-1066120333 doesn't accidentally close us off from the possibility of doing this in future, as sketched in https://rust-lang.github.io/rfcs/3058-try-trait-v2.html#possibilities-for-yeet
- Experiment with the *existence* of syntax for this, to be able to weight the syntax-vs-library tradeoffs better than we can right now.  Notably the syntax (with `do`) and name in this PR are not intended as candidates for stabilization, but they make a good v0 PR for adding this with minimal impact to compiler maintenance or priming one possible name choice over another.

r? `@oli-obk`
The lang `second` for doing this: https://github.com/rust-lang/lang-team/issues/160#issuecomment-1107896716
