9cc29810 - AtomicExpand: Copy metadata from atomicrmw to cmpxchg (#109409)

AtomicExpand: Copy metadata from atomicrmw to cmpxchg (#109409) When expanding an atomicrmw with a cmpxchg, preserve any metadata attached to it. This will avoid unwanted double expansions in a future commit. The initial load should also probably receive the same metadata (which for some reason is not emitted as an atomic).
