[dart2js] Handle ConstantExpression in InlineWeeder.
With constant-update-2018 enabled, ConstantExpression nodes are added to the AST. The defaultNode() implementation increments each node count by 1 whenever we see a ConstantExpression and then does it again when we visit the child DartType, resulting in each ConstantExpression being counted twice. Instead, we should just increment the node counts when we see a ConstantExpression and not visit the children.
