re-stabilize the AVX-512 features that were stabilized in Rust 1.27.0 (#842) 
* re-stabilize the AVX-512 features that were stabilized in Rust 1.27.0

https://github.com/rust-lang/stdarch/pull/739 added per-feature
stabilization of runtime CPU feature detection. In so doing, it
de-stabilized some detection features that had been stable since Rust
1.27.0, breaking some published crates (on nightly). This commit
re-stabilizes the subset of AVX-512 detection features that were
included in 1.27.0 (that is, the pre-Ice-Lake subset). Other instruction
sets (MMX in particular) remain de-stabilized, pending a decision about
whether should ever stabilize them.

See https://github.com/rust-lang/rust/issues/68905.

* add a comment explaining feature detection stability

* adjust stabilizations to match most recent proposal

0bd16446db Fix race condition in feature cache on 32 platforms (#837) 
* Fix race condition in feature cache on 32 platforms

If we observe that the second word is initialized, we can't really
assume that the first is initialized as well. So check each word
separately.

* Use stronger atomic ordering

Better SeqCst than sorry!

* Use two caches on x64 for simplicity

* Add Icelake avx512 features

As documented in https://software.intel.com/sites/default/files/managed/c5/15//architecture-instruction-set-extensions-programming-reference.pdf

* Sort the avx512 feature checks by bit

* Unbreak macos

Force nightly.

5548609204 Add const unstability attributes 
These are needed for rustc to be able to correctly handle stability of constness of intrinsics. Without either `rustc_const_unstable` or `rustc_const_stable` an intrinsic is not const evaluable at all.
