Boqun Feng 978e5a3692 atomics: Add test for atomic operations with _relaxed variants ...

Some atomic operations now have _relaxed/acquire/release variants, this
patch adds some trivial tests for two purposes:

  1. test the behavior of these new operations in single-CPU
     environment.

  2. make their code generated before we actually use them somewhere,
     so that we can examine their assembly code.
