enable outlining atop of new compiler

Note: teh original code has this:

                this.elements.push(new OutliningSpan(
                    /*textSpan:*/ TextSpan.fromBounds(end(startElementPreviousToken), end(endElement)),
                    /*hintSpan:*/ TextSpan.fromBounds(start(node), end(node)),

specifically we use start(node)   not fullStart(node).  Let's keep that logic.
