It does support native C++. I use Refactor! Pro, which does have a DevExpress menu. However, I think the free versions of Refactor! probably don't. The refactorings are available based on your context, e.g., suppose you have:
int count = 5;
If you place the cursor at the start of count you should see a Refactor! smart tag appear. Clicking on this with the mouse will pop up a menu of available refactorings, e.g., "rename."
You can also invoke the refactoring (when available) via a keyboard shortcut. In Options->Keyboard it is assigned to CodeRush.Refactor.
Also I recommend viewing the Refactor! C++ training video.
