This PR adds “sparse casesOn” constructions. They are similar to `.casesOn`, but have arms only for some constructors and a catch-all (providing `t.ctorIdx ≠ 42` assumptions). The compiler has native support for these constructors and now (because of the similarity) also the per-constructor elimination principles.
