Also - add Reference id - fix typo

I seemed to have forgotten that since I am using GET_PROTOCOL attribute for the std usecases, I did not need to close the protocols explicitly. So adding these comments as a note to future self not to waste time on the same thing again. Signed-off-by: Ayush Singh <ayush@beagleboard.org>

…be outside the range of a scalar

fix 2 borrowck issues fixes rust-lang#146467 cc ``@amandasystems`` our understanding here is as follows: region constraints from computing implied bounds gets `ConstraintCategory::Internal`. If there's a higher-ranked subtyping errors while computing implied bounds we then ended up with only `ConstraintCategory::Internal` and `ConstraintCategory::OutlivesUnnameablePlaceholder(_)` constraints. The path was something like - `'placeholderU2: 'placeholderU1` (`Internal`) - `'placeholderU1: 'static` (`OutlivesUnnameablePlaceholder('placeholderU2)`) It's generally somewhat subtle here as ideally relating placeholders doesn't introduce `'static` constraints. Relating the placeholders themselves will always error regardless, cc rust-lang#142623. --- separately fixes rust-lang#145925 (comment) by updating the location for deferred closure requirements inside of promoteds. I am not updating their category as doing so is 1) effort and 2) imo actually undesirable 🤔 see the comments in `TypeChecker::check_promoted` cc ``@lqd`` r? lqd

…alfJung Make missed precondition-free float intrinsics safe So, in my defence, these were both separated out from the other intrinsics in the file *and* had a different safety comment in the stable versions, so, I didn't notice them before. But, in my offence, the entire reason I did the previous PR was because I was using them for SIMD intrinsic fallbacks, and `fabs` is needed for those too, so, I don't really have an excuse. Extra follow-up to rust-lang#146683. r? ```@RalfJung``` who reviewed the previous one These don't appear to be used anywhere outside of the standard locations, at least.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
