Add early return to Styleable::cancelStyleOriginatedAnimations()
https://bugs.webkit.org/show_bug.cgi?id=307711
rdar://170265233
Reviewed by Ryosuke Niwa.
cancelStyleOriginatedAnimations is called frequently during style resolution
and renderer teardown, including on elements that have never had animations.
This function performs cleanup on animation-related data structures. However,
all animation state for an element lives in a single ElementAnimationRareData
container. If no animation data exists for the element, there is nothing to
clean up.
Without an early return, it performs 3 rare data lookups even
when the element has no animation data.
Add an early return when no animation data exists to reduce the amount
of rare data lookups from 3 -> 1.
This is a performance improvement.
