Hash :9e3d7aa0 Message :D3D11: Work around small mipped stencil textures.
AMD has a bug with 2x2 and 1x1 mips of depth/stencil textures. Formats
D24S8 and D32FS8 both seem to render black for the very small mips.
We can work around this by selectively caching a copy of the texture
data that only has depth information, since stencil isn't filterable
in OpenGL ES.
