       * There used to be some confusion regarding the Clear Tile Buffers
       * Z/S bit also being broken, but we confirmed with Broadcom that this
       * is not the case, it was just that some other hardware bugs (that we
       * need to work around, such as GFXH-1461) could cause this bit to behave
       * incorrectly.
       *
       * There used to be another issue where the RTs bit in the Clear Tile
       * Buffers packet also cleared Z/S, but Broadcom confirmed this is
       * fixed since V3D 4.1.
       *
       * So if we have to emit a clear of depth or stencil we don't use
       * the per-buffer store clear bit, even if we need to store the buffers,
       * instead we always have to use the Clear Tile Buffers Z/S bit.
       * If we have configured the job to do early Z/S clearing, then we
       * don't want to emit any Clear Tile Buffers command at all here.
       *
       * Note that GFXH-1689 is not reproduced in the simulator, where
       * using the clear buffer bit in depth/stencil stores works fine.
