I would like to mention one point as a follow-up to the discussion in PR #2982 - the new IR operation I am introducing is technically expressible as a combination of existing ones. This comment from the WebAssembly SIMD operation proposal gives an idea how, but note that pattern-matching would be further complicated by the fact that addition is commutative. Overall, I think that in this case the balance is in favour of introducing a new IR operation.

I agree, the in-terms-of-exsting-ops form is 8 Wasm ops, so this is reasonable to create a new opcode for, I think.
