Redundant BindingFlags

From `TypeExtensions.cs`

```csharp
private const BindingFlags PublicMembersFlag =
BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance;

private const BindingFlags AllMembersFlag =
PublicMembersFlag | BindingFlags.NonPublic | BindingFlags.Static;
```

Note how `BindingFlags.NonPublic` is included in both constants.

Is that just redundant?
