This patch series adds a new debug option to pad each GEM BO
allocated by the brw_bufmgr with pseudo-(weak) random noise values
which are then checked after each batchbuffer dispatch to the kernel.
This can be quite valuable to find diffucult to track down heisenberg
style bug
I really like this in principal. I left comments on patches 2 and 3 which
I think make things better. My comments on 2 are a bit on the bikeshed
side, but I think reasonable.
