[PATCH] D47836: Use SmallPtrSet explicitly for SmallSets with pointer types (NFC).

[Florian Hahn via Phabricator via llvm-commits]

Yeah, I am not really sure there is a strong reason to change it. I just went for SmallPtrSet, because it is much wider used than SmallSet. And using `SmallPtrSetImpl<> &` on a SmallSet looks suprising.
