Yes, sorry, I actually run piglit, but twice on the same binary...

The problem was that last_tile_addr must be invalidated on any change
including flushes.
This was automatic before since we stored it at last_tile->addr, but
now needs to be done explicitly.

I posted a new version that should actually not have regressions on piglit.
