P0439R0 renamed the std::memory_order enumerators when making it a scoped enumeration. The paper makes the old unscoped names available in the global namespace, but not within the scope of the enumeration.For example: std::memory_order::memory_order_consume is no longer well-formed but std::memory_order::consume and std::memory_order_consume are. In order to prevent unnecessary breakage, we should re-add the memory_order_foo names to the enumeration.
