[Mesa-dev] [PATCH 01/12] intel: Add flag intel_context.use_hiz

[chad at chad-versace.us]

From: Chad Versace <chad.versace at intel.com>

Currently, it is always set it to false. Once the HiZ implementation is
complete, it needs to be enabled on Gen >= 5.

Even though support for hiz is present only on gen >= 5, the field belongs
in intel_context, not brw_context, because the functions that interact
with DRI2 and choose buffer formats are passed an intel_context.
