Prepare for the next release

[taiki-e]

It's been over two months since the previous release. There are some improvements and deprecations in the master branch, and it would be nice to release them. Also, there is no breaking change that needs a major version bump.

Changes:

• crossbeam-epoch 0.9.1 -> 0.9.2
  • Add Atomic::compare_exchange and Atomic::compare_exchange_weak. (Add Atomic::compare_exchange(_weak) and deprecate Atomic::compare_and_set(_weak) #628)
  • Deprecate Atomic::compare_and_set and Atomic::compare_and_set_weak. (Add Atomic::compare_exchange(_weak) and deprecate Atomic::compare_and_set(_weak) #628)
  • Make const_fn dependency optional. (Make const_fn crate optional dependency #611)
  • Add unstable support for loom. (Add preliminary support for loom #487)
• crossbeam-utils 0.8.1 -> 0.8.2
  • Deprecate AtomicCell::compare_and_swap. (Deprecate AtomicCell::compare_and_swap #619)
  • Add Parker::park_deadline. (Updates to Parker #563)
  • Improve implementation of CachePadded. (CachePadded: update alignment based on golang's CacheLinePadSize #636)
  • Add unstable support for loom. (Add preliminary support for loom #487)

I'd like to merge #658 first or at the same time.

#658 merged, unblocking

How about waiting for #578, #591, #655? After that, I think it's time to release a new version!

[taiki-e]

#591 and #655 have been merged. As for #578, some tests hang when using the latest Miri, so I'd like to postpone it for now. (Currently, I don't have the bandwidth to investigate it.)
