@Mark-Simulacrum Can I get a perf run?

Not currently. Perf is down while we transition to the new collector/frontend, but that should be a relatively temporary event. Once it's back up and running, sure -- it'll be a day or so, and then please ping me again if I haven't posted anything.

Please rebase onto master to pick up #46354. Once that's in, I think this should work.

Build queued. Should be available on perf.rlo at http://perf.rust-lang.org/compare.html?start=0a2e9ade83ff253bb489c63a95b1f499c5e0916f&end=04c8514ef729c50d18533b9b435fb0659afd07da&stat=instructions%3Au in at most 4 hours, likely less.

@Mark-Simulacrum Let's run perf again, now with thread-safe types :)

Here are the result:

The 30% overhead which I got last time seems to have disappeared.

@Zoxc just checking in for triage and wondering where this is up to? I can see there are merge conflicts, but once those are resolved is this ready for review?

Auto merge of #46564 - Zoxc:rayon-queries, r=<try>

WIP: Parallelize passes using rayon

This builds on #46193 and #45912 and actually makes code run in parallel. This is not quite ready yet since `rustc` is not yet completely thread safe. It also uses a rough fork of rayon which uses fibers/stackful coroutines.
