Subject: Disallow null as a named metadata operand. Make MDNode::destroy
 private. Fix the one thing that used MDNode::destroy, outside of MDNode
 itself.

One should never delete or destroy an MDNode explicitly. MDNodes
implicitly go away when there are no references to them (implementation
details aside).
