    We use the parameter `j` to reduce the number of `instantiate*` invocations.
    It is the same approach we use at `forallTelescope` and `lambdaTelescope`.
    Given `getSubgoalsAux args j subgoals instVal type`,
    we have that `type.instantiateRevRange j args.size args` does not have loose bound variables. -/
