We're about to start letting the intel_obj->_Format be the "real"
texture format. For depth/stencil textures, this may be a combined
depth stencil format. For ETC2 on gen7 and earlier, this will be the
actual ETC2 format. This makes a bit more GL sense but means we have to
be careful in state upload.
