Tune the inlinability of `unwrap` Fixes #115463 cc `@thomcc` This tweaks `unwrap` on ~~`Option` &~~ `Result` to be two parts: - `#[inline(always)]` for checking the discriminant - `#[cold]` for actually panicking The idea here is that checking the discriminant on a `Result` ~~or `Option`~~ should always be trivial enough to be worth inlining, even in `opt-level=z`, especially compared to passing it to a function. As seen in the issue and codegen test, this will hopefully help particularly for things like `.try_into().unwrap()`s that are actually infallible, but in a way that's only visible with the inlining. EDIT: I've restricted this to `Result` to avoid combining effects |
