Hmmm... for me performance was first impacted with a77e813d, and building Mesa
from the commit before that one (3b1c1f02) still gave me the faster performance
Mesa had jumped to in January.  (I only reverted the other 3 commits because
they depended on a77e813d, and I did not know how to preserve them without it.)
 Because of this, I was never really able to separate the impact of 077c448d by

As described above, just moving from 3b1c1f02 to a77e813d reduces (for me) the
frame rate in 'torcs' by roughly 30%.
