  Re-re-land "D3D11: Implement dirty bits for VertexArray11.""
  
  Translated attributes are now stored in the VertexArray11 in a cache,
  and only updated when dirty bits change. Currently dynamic attributes
  must be re-translated every call, so these are stored in a list and
  processed repeatedly.
  
  This skips doing a lot of the VertexDataManager work for vertex
  attributes that don't change between draw calls.
  
  Current value attributes, which correspond to disabled attributes that
  the program will pulls vertex data from, are owned by the Context, so
  these need to be handled outside of the VertexArray11.
  
  Further changes will be necessary to reduce the redundant work we do in
  the InputLayoutCache. We shouldn't need to re-check the cache if
  nothing relevant changed.
  
  This give about a 23% performance improvement on the draw call
  benchmark on my machine.
  
  Re-land with a fix for the start vertex offset.
  
  Re-re-land with a fix for using XFB with deleted buffers.
