This patch is based on the patch created by Makoto Kato-san. `Range` and `StaticRange` have common base interface, `AbstractRange`. https://dom.spec.whatwg.org/#abstractrange This interface has simply returns `startContainer`, `endContainer`, `startOffset`, `endOffset` and `collapsed`. Different from the original patch's approach, this patch moves related members in `nsRange` to `AbstractRange` since this approach avoids virtual call cost. Additionally, this patch makes them not throw as declared by the spec. As far as I know, the destruction cost of `ErrorResult` may appear in profile so that we should avoid creating the instance if we can avoid it. Unfortunately, the instance size of `nsRange` becomes larger with this patch. The size is changed from 176 to 184. I.e., now, `nsRange` requires bigger chunk.
