Title: SI-6567 Warning for Option(implicitView(foo))

I've seen the reported problem before in the wild. It seems
worthy of a special warning, so long as we advocate `Option.apply`
as an alternative to `if (x == null) Some(x) else None`.

It is behind `-Xlint` at the moment, an option that could do with
some promotion.
