This operation is used to materialize a tensor of a particular

shape. The shape could be specified as a mix of static and dynamic

values.

The use of this operation is to be an `init` tensor for Linalg

structured operation on tensors where the bounds of the computation

depends on the shape of the output of the linalg operation. The result

of this operation will be used as the `init` tensor of such Linalg

operations. To note,

- The values in the tensor materialized is not used. Any operation to which this is an init tensor is expected to overwrite the entire tensor.
- The tensor is materialized only for the shape of the output and to make the loop bounds depend only on operands of the structured operation.

Based on (1) and (2) it is assumed that these operations eventually go

away since they are only used in `dim` operations that can be

canonicalized to make this operation dead. Such canonicalization are

added here too.
