Reviewed by Kenneth Rohde Christiansen.
Changed the layout algorithm for rows to avoid unnecessary recursion
into child rows. This solves the long rendering time experienced in
https://bugs.webkit.org/show_bug.cgi?id=43462 as well as reports in
various other bugs. The change in the algorithm required some
tweaks to other rendering objects to make sure that the baseline
alignment still works.
In addition, an attempt was made to go through the various
rendering objects for MathML and reduce unnecessary calls that
mark the tree in need of layout.

+ Changed the layout algorithm for rows to avoid unnecessary recursion
+ into child rows. This solves the long rendering time experienced in
+ https://bugs.webkit.org/show_bug.cgi?id=43462 as well as reports in
+ various other bugs. The change in the algorithm required some
+ tweaks to other rendering objects to make sure that the baseline
+ alignment still works.
+
+ In addition, an attempt was made to go through the various
+ rendering objects for MathML and reduce unnecessary calls that
+ mark the tree in need of layout.
