First, left/right node accessors are not used so that we can get rid of them.
However, we should have similar methods which can retrieve original node and
new node. Therefore, this adds GetNewContent() and GetOriginalContent().

Next, SplitPoint() should return both EditorDOMPoint and EditorRawDOMPoint
for avoiding unnecessary conversion from EditorRawDOMPoint to
EditorDOMPoint. Therefore, this patch makes it a template method too.

Finally, this patch adds helper methods to get point of each related content.
E.g., AtNewContent() corresponding to GetNewContent().
