Auto merge of #68772 - matthewjasper:relate-opt, r=davidtwco
Avoid exponential behaviour when relating types When equating bound types we check subtyping in both directions. Since closures are invariant in their substs, we end up comparing the two types an exponential number of times. If there are no bound variables this isn't needed. Closes #68061
