[Mesa-dev] [PATCH 5/5] i965: use ASTC5x5 workaround in brw_compute

[kevin.rogovin at intel.com]

From: Kevin Rogovin <kevin.rogovin at intel.com>

Perform the ASTC5x5 workaround tasks for compute; note that
the function does not do anything and immediately returns
if the bug is not present on the hardware.
