This commit adds support for fetch-and-op atomics. This is needed because and and or are irreversible operations so there needs to be a way to get the old value atomically. These are also the only semantics supported by C11 (there is not atomic_op_fetch, just atomic_fetch_op). The old op-and-fetch atomics have been defined in terms of fetch-and-op.
