I think that after the valtree PR we should move promoteds out of ty::ConstKind::Unevaluated and directly as an option in mir::Constant, as that's the only place they can occur.

PredicateKind::ConstEvaluatable could take a ty::Unevaluated, but considering that it can't take promoteds... maybe not

rebased this on #83086 for now, as there are no merge conflicts there this might not actually be needed.

uh... I don't see how these two PRs relate except that both of them are a prerequisite for making substs optional ^^

@oli-obk was that intended as an r=me?

I think it makes sense to merge this change as is.
