REGRESSION (r264856): updating easing on accelerated animation results in incorrect playback https://bugs.webkit.org/show_bug.cgi?id=215853 <rdar://problem/67815853> Reviewed by Simon Fraser. Source/WebCore: Stop accelerated animations if the timing function has changed in a way that makes it so that it should no longer play accelerated, but otherwise simply update their timing properties such that may keep playing.
