Change TileOperand to a view of a tile object

* TileOperand instead of being the tile object now is only a view
  of a tile object.
  - declare_tile now returns a TileOperand object, not a reference
    to a TileOperand object.
  - This is to prepare for the posibility that the users need
    to perform operations on part of a tile (e.g. a scalar value,
    a vector, a sub-tile).
