I don't think I agree. APInt as an interface type won't really save any typing, so what advantage would this compromise have? It's about the same to write `SrcOp(APInt(x))` vs `SrcOp(int64_t(x))`, but the APInt version is more expensive and if we're not actually handling arbitrary precision it's quite a bit more confusing.
