/* For gen12 we set the streamout buffers using 4 separate commands

* 3DSTATE_SO_BUFFER apart from the SOBufferIndex field, so for now we use the
* 3DSTATE_SO_BUFFER command, but change the 3DCommandSubOpcode.
* SO_BUFFER_INDEX_0_CMD is actually the 3DCommandSubOpcode for
* 3DSTATE_SO_BUFFER_INDEX_0.
