5bd5ea21ea Remove unwrap_none as it won't be stabilized. 
This upgrades to the latest rustc to be able to use try_insert()
instead.

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.

a2fa80d277 Auto merge of #1641 - JCTyblaidd:update_release_sequences, r=RalfJung 
Weaken release sequences to match the C++20 memory model

See [Weaken Release Sequences](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0982r1.html), since the exception for relaxed writes on the same thread as a release write not blocking release sequences was removed in the C++20 memory model compared to the C11 memory model the paper was based on. The implementation can be updated and simplified to match this.  [Rust is currently specified to use the C++20 memory model](https://doc.rust-lang.org/std/sync/atomic/index.html).

d473242ecd Auto merge of #1617 - JCTyblaidd:data_race_detector, r=RalfJung 
Add simple data-race detector

Partially fixes data-race detection, see #1372, based on Dynamic Race Detection for C++11

- This does not explore weak memory behaviour, only exploring one sequentially consistent ordering.
- Data-race detection is only enabled after the first thread is created, so should have minimal overhead for non-concurrent execution.
- ~~Does not attempt to re-use thread id's so creating and joining threads lots of time in an execution will result in the vector clocks growing in size and slowing down program execution~~ It does now
