 It's not clear whether using `instance_cache` is a sensible choice here.
 In particular, we need to use these tactics below when the algebraic instances are local variables
 that aren't in the "real" instance cache (the one used by `tactic.reset_instance_cache`).

 This file provides instances on `x y : Q($α)` such that `x + y = q($x + $y)`.

These are taken from #5863, as the mathport output is not ready, but would be useless anyway.
