// ASM stream Phase E — x86_64 multi-output asm: `divq` produces quotient in rax
// and remainder in rdx, returned as a `(quot, rem)` tuple. Two `={rax}`/`={rdx}`
// value outputs ⇒ LLVM returns a `{ i64, i64 }` struct, which IS sx's tuple
// representation (so `q, r := …` destructures it directly). x86-pinned via
// `.build`: ir-only on a non-x86 host (the `.ir` snapshot locks the struct
// return + `%[name]` rewrite); runs natively on x86_64-linux. See 1647 for a
// multi-output example that executes on aarch64.
