  11. Revert "Set test flag when rustdoc is running with --test option" 

    This reverts commit 8ed2292.

It caused doctests in this repository to no longer be tested including all of the core crate.

  12. Beta backport of: Auto merge of rust-lang#61754 - nikomatsakis:trait-… 

    …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.
