1 ... 3 (numeric literal followed by three dots and a numeric literal) indicates a pattern that matches any literal in the given range.

I hope the use of ... here doesn't conflict with macro syntax.

Add SHM_ANON for FreeBSD

This is a constant for `shm_open` that is used instead of the address to create an anonymous shared memory mapping.

* 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
