I would drop the backport of #59752 and as it will land on beta soon anyway and there might be issues with it (see #62088). Not really sure why this was nominated in the first place.

The most recent travis failure is from #61199. The change from #61161 (comment) will need to be backported as well. It was part of #61199 but got lost in a rebase.

I beta-nominated PR #59752 due to this comment. but that comment is making an assertion about PR #59800, which you (@Zoxc) authored, so maybe I misunderstood the comment, or the comment itself was erroneous?

This is waiting on decisions on #62055 and #61754.

and I retracted the nomination of #62055.

This reverts commit 8ed2292.

It caused doctests in this repository to no longer be tested including all of the core crate.
…caching-perf-3, r=pnkfelix

create a "provisional cache" to restore performance in the case of cycles

Introduce a "provisional cache" that caches the results of auto trait resolutions but keeps them from entering the *main* cache until everything is ready. This turned out a bit more complex than I hoped, but I don't see another short term fix -- happy to take suggestions! In the meantime, it's very clear we need to rework the trait solver. This resolves the extreme performance slowdown experienced in rust-lang#60846 -- I plan to add a perf.rust-lang.org regression test to track this.

Caveat: I've not run `x.py test` in full yet.
