Summary: 64-bit WebAssembly (wasm64) is not specified and not supported in the WebAssembly backend. We do have support for it in clang, however, and we would like to keep that support because we expect wasm64 to be specified and supported in the future. For now add an error when trying to use wasm64 from the backend to minimize user confusion from unexplained crashes.
