So, the Fuscia builder thinks that its atomic inline width is zero, which leads to a warning and because we compile with `-Werror` it turns into an error. Any suggestions for this? I don't know the platform, but a maximum atomic inline size of zero seems weird. This is usually set with `MaxAtomicInlineWidth = TargetPointerWidth;` in `clang/lib/Basic/Targets/`. Does anyone who knows Fuscia know if it's true that every single atomic there goes through compiler-rt? Otherwise I think the solution is to ignore the warning.
