SI-7294 Treat TupleN as final under -Xfuture
For the purposes of checkability warnings. This will
warn in case of:
scala> (1, 2) match { case Seq() => 0; case _ => 1 }
res9: Int = 1
Given how often Tuples are used as scrutinees, this is
a highly desirable place to warn.
I was orginally going to unlock this under -Xlint, and
could be easily convinced to go that way, given that
-Xfuture is a less popular option.
