It looks like this code was accidentally dropped at some point(in a
slightly different form), so add it back. The gist is that if we know
the allocation will be one single chunk, then we can just annotate the
BO with I915_BO_ALLOC_CONTIGUOUS, even if the user doesn't bother. In
the future this might prove to be potentially useful.
