- Redocument memory ordering from "no ordering" to "acquire-release". (No functional change: both LOCK WHATEVER on x86, and LDAXR/STLXR loops on ARM64, already have this property.) - Remove IncUnlessZeroInt32 and DecUnlessOneInt32, which were only faster than the equivalent loops using sync/atomic before the Go compiler inlined non-unsafe.Pointer atomics many releases ago.
