Hiroyuki Ikezoe 0715b582fd Bug 1406211 - Check whether the frame is one of continuation or ib-split-sinbling frames for animating element in nsIFrame::HasOpacityInternal(). r=dbaron ...

We need this change to generate nsDisplayOpacity for the continuation or
ib-split-sibling frames other than the first continuation so the opacity
animation on the continuation frames runs on the compositor.
When we generate an nsDisplayOpacity, the animation runs on the compositor,
but when we don't, the animation never updates since the animation is throttled
on the main thread.
