2eae474673 Auto merge of #2197 - RalfJung:round-robin, r=RalfJung 
make Miri's scheduler proper round-robin

When thread N blocks or yields, we activate thread N+1 next, rather than always activating thread 0. This should guarantee that as long as all threads regularly yield, each thread eventually takes a step again.

Fixes the "multiple loops that yield playing ping-pong" part of https://github.com/rust-lang/miri/issues/1388.
`@cbeuw` I hope this doesn't screw up the scheduler-dependent tests you are adding in your PR.

run Clippy on CI

and fix some things it complains about. Also use `rustup-toolchain` script on CI (reduces code duplication, and good thing to make sure it keeps working, since we recommend it in the docs).

I left `ui_test` out for now; I'll leave those nits to `@oli-obk.` ;)
