While following change:
i965/tex: Use blorp texture upload for all CCS_E textures 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().

improved GLB 2.7 Fill hugely and SynMark PSPom slightly on all GEN9+ SoC platforms, it also clearly regressed few tests on all GEN9+ platforms.
These regressions are (depending on platform):
- 3-5% in GfxBench v4 ALU2 onscreen & offscreen tests
- 2-6% in SynMark v7 TexFilterTri test
