Using the term for MIR is okay, because it does not have a pre-existing notion of canonical form. Doing the same for IR is not okay, because it already has a canonical form and this pass does not produce it. Calling this `ir-normalizer` instead of `ir-canonicalizer` should convey about the same intent without overloading an existing, widely used term.
