drm/i915: Allow execbuffer to use the first object as the batch
Currently, the last object in the execlist is the always the batch. However, when building the batch buffer we often know the batch object first and if we can use the first slot in the execlist we can emit relocation instructions relative to it immediately and avoid a separate pass to adjust the relocations to point to the last execlist slot.
