Can we also test the case with the (local.get $x) on the RHS? Or do we already have coverage for that?

Yes, that is what OPTIN - running optimize-instructions first - tests. It canonicalizes the order of such things, and that canonical order is what matters.

When seeing if
x == Cprovesx >= D, we can just applyC >= D.And, in reverse,
x >= Dmay implyx != CifC < D.
