[libcxx-commits] [libcxx] Add 64bit atomic check in the is_always_lock_free_pass test. (PR #111540)

[via libcxx-commits]

https://github.com/simpal01 created https://github.com/llvm/llvm-project/pull/111540

Currently this test is completely xfailed as part of the patch https://github.com/llvm/llvm-project/pull/106077. But this test works on A and R profile, not in v7M profile. Because the test contain cases in which  m-profile will fail for atomic types greater than 4 bytes in size.
