[Mesa-dev] [PATCH v2 00/12] i965/gen7+: Implement fast color clears.

Changes since the previous version:

- Because of objections, I've dropped the patch "intel: Create
  intel_miptree_get_region() to prepare for fast color clear."
  Instead of using an accessor function to ensure that appropriate
  resolves are performed before any access to
  intel_mipmap_tree::region, I've simply placed the resolves at the
  points where they are needed, as we do for HiZ.

- Rebased on top of Eric's intel_miptree_blit code--this reduced the
  number of places where resolves had to be performed.

- Added a perf_debug message if the client tries to clear to a color
  that isn't compatible with the fast color clear mechanism.

- Ensured that BRW_NEW_SURFACES is flagged when a fast clear occurs,
  so that the MCS buffer pointer and the fast clear color will be
  properly delievered next time the surface is used.

- Fixed some build warnings.

- Added patch 01/12, which avoids a corner case bug that was present
  in the previous series.
