Optimize comparing various RenderStyle properties
https://bugs.webkit.org/show_bug.cgi?id=286868
rdar://144024685
Reviewed by Sam Weinig.
We can optimize comparisons of things like column span, border colors, content
data etc
by first comparing the pointers (`m_nonInheritedData` etc) before then comparing
the values. This is done by adding some helper functions on RenderStyle.
Also optimize `RenderStyle::changeAffectsVisualOverflow()` by grouping and
reordering
comparisons.
