   Allocate a tile of zero-initialized items.
   
   Every element is set to the zero value of ``dtype``. Scalar, vector, matrix, and
   Warp struct element types are all zero-filled component-wise.
   
   :param shape: Shape of the output tile. Must be a compile-time constant.
   :param dtype: Data type of output tile's elements. Must be a compile-time constant.
   :param storage: The storage location for the tile: ``"register"`` for registers or
                   ``"shared"`` for shared memory. Must be a compile-time constant.
   
   :returns: A zero-initialized tile with the requested shape and data type.

   Allocate a tile of zero-initialized items.
   
   Overload for 1D tiles: ``shape`` is the number of elements, equivalent to passing
   ``(shape,)``. See the overload taking a tuple-valued ``shape`` argument for usage
   details and an example.
