Per https://github.com/WebAssembly/function-references/pull/76, call_ref and return_call_ref should consume type immediates specifying the signature of the funcref. This is a breaking change. To ease the migration, this patch introduces a temporary alternative binary encoding for call_ref: - 0x14 continues to *not* take a type immediate for now. - 0x17 (formerly "let") is the new call_ref *with* type immediate. Module producers are encouraged to emit this encoding ASAP. - After a few weeks of transitionary period, we'll update 0x14 to take a type immediate as well. At this point, module producers will be encouraged to switch back to 0x14. - After a few more weeks of transitionary period, we'll drop 0x17 again. We're not doing the same dance for return_call_ref because it currently has no uses that we know of.
