Closes #.

Rationale for this change

See issue9812 for rationale.

What changes are included in this PR?

When an equality expression is added to the EquivalenceProperties. In light of this information, we can deduce new information about ordering and constantness. This PR adds this support.

With the PR we have this support, in terms of behaviour. However, current solution doesn't update state and cannot generalize well.

Are these changes tested?

There is an additional TestCase, that showcases increased coverage with this implementation (That test case fails in main branch).

Are there any user-facing changes?
