[Mesa-dev] [PATCH 19/64] isl/state: Set SurfaceArray based on the surface dimension

[Jason Ekstrand]

According to the PRM, you can't set SurfaceArray for 3D or buffer textures.
There doesn't seem to be a good reason not to set it when we can.  On the
other hand, if we don't set it we can end up getting strange results for
1-layer array textures such as textureSize() returning the wrong results.
