[cc] Dont throw away tiles that stop moving

[cc] Dont throw away tiles that stop moving

The check being removed here basically says "if you're offscreen, and have no time to visible, then you should go in the never bin."

The problem is that when a layer stops moving, then its offscreen tiles are put in never bin. That means that we lose all those tiles we put effort into painting. This increases the frequency at which one sees blurry tiles after the page goes stationary.
