This mirrors @mcfi's MSVC-PR-567635 "Leverage clang builtins
__atomic_load_n/__atomic_store_nfor more efficient acquired loads and released stores on Arm64" as of Iteration 13. His description:This improved a benchmark score by ~2.8% on real hardware.
Resolves llvm/llvm-project#62103 because we're going to use Clang's builtins now.
Works towards #1133.
