Cycles: Report currently sampling tile when CPU is working on the last tile 

This is mainly useful for the render farms output when logging might stop at
the "Path Tracing Tile N/N" string, which makes it a bit difficult to follow
what exactly is happening (node going crazy, hardware issues or just last tile
is too much heavy).

This is more like an experiment, might be changed in the future.
