Manos Koukoutos 1ba5766f5e [wasm][gc] Implement struct.set and switch struct.get to optref ... Work towards adding heap-allocated object support for wasm, according to the gc proposal. Changes: - Implement subtyping for reference types (ref s) and (optref s), where 's' is a struct type. This CL does *not* implement subtyping between struct and function types. Also, it does not handle i31refs and eqrefs. - Implement struct.set. - Change struct.get to accept an optref as argument, as required by the standard. - Allow locals to store objects of ref and optref types. - Add a test for struct.set and optref locals. Modify the test for struct.get accordingly.
