Subject: [PATCH] Improved Visual Studio visualization of OpaquePtr

Create a special visualizer for OpaquePtr<QualType> because the
standard visualizer doesn't work with OpaquePtr<QualType>
due to QualType being heavily dependent on traits to be pointer-like.

Also, created an identical visualizer for UnionOpaquePtr
