  Log Message:
  -----------
  [mlir] Add primitive transform pattern to rewrite linalg.fill into vector.broadcast form.

Summary:
This diff adds a transformation patter to rewrite linalg.fill as broadcasting a scaler into a vector.
It uses the same preconditioning as matmul (memory is contiguous).
