IR: Simplify uniquing for MDNode Change uniquing from a `FoldingSet` to a `DenseSet` with custom `DenseMapInfo`. Unfortunately, this doesn't save any memory, since `DenseSet<T>` is a simple wrapper for `DenseMap<T, char>`, but I'll come back to fix that later. I used the name `GenericDenseMapInfo` to the custom `DenseMapInfo` since I'll be splitting `MDNode` into two classes soon: `MDNodeFwdDecl` for temporaries, and `GenericMDNode` for everything else. I also added a non-debug-info reduced version of a type-uniquing test that started failing on an earlier draft of this patch.
