areIdenticalElements is copied from ApplyStyleCommand, I'll be sharing it between ApplyStyleCommand and ReplaceSelectionCommand in my final patch.

This patch currently requires 3 rebaselines: editing/pasteboard/4242293-1.html, editing/pasteboard/copy-paste-bidi.html, and editing/selection/replace-selection-crash.html.  The first two tests need to be converted to dumpAsMarkup or dumpAsText tests first.  But changes are good as far as I looked at the render tree.

This patch does not fix the bug 26483 because of the bug 34564.  We could work-around the issue by handling style spans before pasting.  But the correct thing to do is not to wrap everything with style-spans.  It shouldn't be too hard to push styles to each element in the fragment and have ReplaceSelectionCommand remove all redundant styles at the pasting stage.  But we should probably do that in a separate patch.
