This patch separates out the portions of gen6_blorp_emit_batch_head()
that emit 3DSTATE_MULTISAMPLE, 3DSTATE_SAMPLE_MASK, and
STATE_BASE_ADDRESS. This paves the way for making the blorp code work
on Gen7, where additional command packets
(3DSTATE_PUSH_CONSTANT_ALLOC_VS and 3DSTATE_PUSH_CONSTANT_ALLOC_PS)
need to be emitted before 3DSTATE_MULTISAMPLE.
