This PR cherry-picks #4959's fix onto the 1.0.0 release branch in order to facilitate a point-release. The bug affects
atomic_casusage on aarch64. This is not reachable from Wasmtime in the default configuration, but may affect other users of Cranelift (e.g.cg_clif) and any uses of Wasmtime with the atomic-operation extensions enabled.
