// issue #107899
// We end up relating `Const(ty: size_of<?0>, kind: Value(Branch([])))` with
// `Const(ty: size_of<T>, kind: Value(Branch([])))` which if you were to `==`
// the `ty` fields would return `false` and ICE. This test checks that we use
// actual semantic equality that takes into account aliases and infer vars.
