There's a lot to be said for following the existing practice, so feel
free to ignore this, but SmallVectorImpl isn't really a very indicative
name for how it's used in the first place. It's just ubiquitous enough
that it isn't worth changing. Maybe a better name from the get-go for
SmallPtrSetImpl would be worthwhile?

On the other hand, it probably isn't worth bikeshedding about a perfect
name for this.
