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.
