We're already paying for the extra look at stuff, what if we add a second attribute for things that we always want to inline, but are also fine with generic calls not getting inlined? Can we save a bunch of code and functions calls in derived Ords and such? Is it worth the extra overhead of normalizing more calls?

Overall result: ❌✅ regressions and improvements - please read the text below

Benchmarking this pull request means it may be perf-sensitive – we'll automatically label it not fit for rolling up. You can override this, but we strongly advise not to, due to possible changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please do so in sufficient writing along with @rustbot label: +perf-regression-triaged. If not, please fix the regressions and do another perf run. If its results are neutral or positive, the label will be automatically removed.
