The __DRI_USE_INVALIDATE extension was added in May 11th, 2010 by commit
4258e3a2e1c327. At this point, it's unlikely that anyone's using the
right mix of new and old components to hit this path. Deleting it
removes an untested code path and cleans up the driver a bit.

I'm guessing this would break if you had an early-2010 X server or libGL
and modern i965_dri.so. I'm not sure how to properly require this extension
to be present (and fail loading otherwise?). Any advice?
