Also:
 - Disable some Feature Level 9_3 tests that trigger SDK messages
 - Fix a debug object name issue. If you try to assign a debug name
   to an object twice then you get an SDK warning message. This can
   occur if you 'create' two objects (e.g. Rasterizer States) with
   identical DESCs on the same device, since D3D11 can optimize
   this and return the same object both times.
 - Disable the message checks in Line Loops tests, since the tests
   trigger incorrect D3D11 SDK messages on Win7 machines
