I'm trying to remove the redirection in SmallSet.h:
template <typename PointeeType, unsigned N>
class SmallSet<PointeeType*, N> : public SmallPtrSet<PointeeType*, N>
{};
to make it clear that we are using SmallPtrSet. There are only
handful places that rely on this redirection.
This patch replaces SmallSet to SmallPtrSet where the element type is
a pointer.
