Consider merging https://chromium.googlesource.com/chromium/blink/+/2e53720ae89d22d963aae65fe2de1d4d82cbf3c2 Iterating the children is a waste if we're already going to recalc everyone like in a Force situation or if we know that no children needStyleRecalc(). We should skip all the checking in these cases. I also refactored the loop into checkForChildrenAdjacentRuleChanges() since recalcChildStyle was getting too long.
