I hadn't added folding for MGuardObjectIdentity before, because I thought a constant object would be unlikely. Turns out it's actually super common for calls in self-hosted JS. For calls we will bake in the callee via GetIntrinsic. The guard comes from the normal transpiled CacheIR for specialized calls.
