inSynchronizationOfLazyAttribute is making setAttributeInternal incomprehensible

[Ryosuke Niwa]

inSynchronizationOfLazyAttribute is evaluated 4 times in various conditions even though
all can just call ensureUniqueElementData().attributeAt(index).setValue(newValue) and exit early when it's true.

Just do that so that the rest of code is more readable.

I think you have a bug here. If there is an Attr node, you will no longer reset its text children.

It comes from http://trac.webkit.org/changeset/139100. I can add a comment if you'd like.
