Opcode for delegate

[takikawa]

In #137 it's mentioned that the opcode for delegate needs to be decided. Has there been any discussion of that yet?

As mentioned in #137, the 0x0? opcodes are used up. I believe the V8 code is currently using 0x16 as a placeholder, but I think that and 0x17 are used by the function references proposal.

It looks like 0x18 or 0x19 may be available though based on looking through the current proposals.

Following V8 implementation, I was tentatively using 0x16 in my toolchain implementation, but given that it is already takne, we should probably change it to 0x18 or 0x19 as you suggested. How about 0x18? @thibaudmichaud

Thanks for pointing out the conflict with function references, @takikawa. 0x18 sounds good.
