Merge commit 4bb2416d42eb from llvm-project (by Jessica Clarke):
[builtins][AArch64] Implement _sync out-of-line atomics
Whilst Clang does not use these, recent GCC does, and so on systems such
as FreeBSD that wish to use compiler-rt as the system runtime library
but also wish to support building programs with GCC these interfaces are
needed.
This is a light adaptation of the code committed to GCC by Sebastian Pop
<spop@amazon.com>, relicensed with permission for use in compiler-rt.
