This patch does two things, to fix #23209:
* It improves SpecConstr so that it no longer quantifies over
coercion variables. See Note [SpecConstr and casts]
* It improves the rule matcher to deal nicely with the case where
the rule does not quantify over coercion variables, but the the
template has a cast in it. See Note [Casts in the template]
