Matt Arsenault 9cc298108a 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).
