Cycles: Force bottom-to-top tile order for viewport rendering
This commit overrides the user's choice of tile order in the case of viewport
rendering and always uses bottom-to-top instead.
This was already done until the TileManager redesign, but since it removed the
distinction between viewport and regular rendering
in the manager, the viewport was now also using the selected order. Since this
requires sorting of the generated tiles,
it slows down rendering a bit. With the forced bottom-to-top order, this
sorting step can now be avoided again.
Since the tile order is invisible anyways for viewport rendering, this commit
won't have any impact on users (apart from a slight speedup).
