Also, note that these aren't C11 atomics, which would be `atomic_store` and `atomic_load`, without the `__` prefix. Underscore prefixed atomics are compiler builtins.
I'm not particularly opposed to the idea, but without a convincing case for it I'm not sure further modification will be well received. (I'm not a maintainer, so maybe ask for others' opinion.)
Maybe when we drop support for GCC <8, then `__sync_` variants as well as open-coded inline asms could be dropped at once, although we may still need a stronger case for it.
Note that the 32-bit atomics have been effectively tested for years. ReadNoFence64 was relatively new though.
