bors a0485c5a90 Auto merge of #1686 - thomcc:cmpxchg_weak, r=oli-obk
Add random failures to compare_exchange_weak

In practice this is pretty useful for detecting bugs.

This fails more frequently than realistic (~~50%~~ (now 80%, controlled by a flag) of the time). I couldn't find any existing code that tries to model this (tsan, cdschecker, etc all seem to have TODOs there). Relacy models it with a 25% or 50% failure chance depending on some settings.

CC `@JCTyblaidd` who wrote the code this modifies initially, and seems interested in this subject.

bors ba244e3e7c Auto merge of #1679 - hyd-dev:min-const-generics, r=RalfJung
Remove `#![feature(const_generics)]` and `#![allow(incomplete_features)]`

`#![feature(min_const_generics)]` has been [stabilized](https://github.com/rust-lang/rust/pull/79135), so I removed `#![feature(const_generics)]` and `#![allow(incomplete_features)]` (I assume Miri is not built by the beta bootstrap compiler so it's fine to just remove them).

The test [`tests/run-pass/specialization.rs` also has a `#![allow(incomplete_features)]` for `#![feature(specialization)]`](https://github.com/rust-lang/miri/blob/9949d9e4/tests/run-pass/specialization.rs#L1-L2). I think that can be removed and `#![feature(specialization)]` can be replaced with `#![feature(min_specialization)]`, but I'm not sure whether I should do that because it's a test. Feel free to ask me to remove it if it's fine to do so.
