When a SEND instruction is a EOT, the scoreboard lowering will not allocate a new SBID for it, since nothing needs to wait for it. In Gfx12 this allowed the SEND to get out-of-order $.dst or $.src dependencies. Starting on Xe2+ this is not supported anymore, in favor of supporting more combined modes.
