From: Jason Ekstrand <jason.ekstr...@intel.com>
This improves the FillTex benchmark in GLBench 2.7 by 30% on my Broxton.
On Ken's Broxton which only has single-channel ram, it improves by 210%.
v2 (Ken): Check mt->aux_usage == ISL_AUX_USAGE_CCS_E rather than using
intel_miptree_is_lossless_compressed().
