From how I understand, this is upper bounded by the type of the decl (the
number of indirections).
Is it reasonable to expect a low number of indirections? Like 1 or 2 for most
cases? I figure, if this is true, we should use an llvm::SmallVector of 1 or 2
-- to avoid going to the heap every single time.
We could also suffix this alias with `Vec` -- mostly to contrast it with the
similar `EntityPointerLevelSet` because they have a different semantic.
