interpret: don't rely on ScalarPair for overflowed arithmetic This is for https://github.com/rust-lang/rust/pull/97861. Cc `@eddyb` I would like to avoid making this depend on `dest.layout.abi` to avoid a branch that we are not usually covering both sides of. Though OTOH this seems like fairly straight-forward code. But let's benchmark this option first to see how bad that extra `force_allocation` really is. |
