  Log Message:
  -----------
  [mlir][linalg] Let tile and fuse fail for tile sizes zero.

Adapt `tileConsumerAndFuseProducers` to return failure if the generated tile loop nest is empty since all tile sizes are zero. Additionally, fix `LinalgTileAndFuseTensorOpsPattern` to return success if the pattern applied successfully.
