This change is a renaming with no functional changes. It includes the following renames: * `val` for arguments that replace the atomic value (e.g., `Store`). * `delta` for arguments that offset the atomic value (e.g., `Add`). * `old`, `new` for arguments to `CAS`. * `old` named return from `Swap`. * `swapped` for named return from `CAS`. This also matches the names used in the stdlib atomic interface: https://golang.org/pkg/sync/atomic/
