Matthijs Kooijman d1d1de7f39 Revert r53606. It turns out that explicitely tracking the liveness of the
return value as a whole in deadargelim is really not needed now that we simply
rebuild the old return value and actually prevents some canonicalization from
taking place.

This revert stops deadargelim from changing {i32} into i32 for now, but I'll
fix that next.
