Web Inspector: debuggerPresentatioModel.linkifyLocation leaks updateAnchor closure...

Web Inspector: debuggerPresentatioModel.linkifyLocation leaks updateAnchor closure instances.
https://bugs.webkit.org/show_bug.cgi?id=69146

In many places we use linkifyLocation function to produce a link node which updates automatically when the source file is changed on the fly.
Such changes happen when we use pretty print or another operation that changes the source code somehow.
linkifyLocation associates a new instance of updateAnchor closure with the each link node and add the closure to the SourceMappingUpdated event's list.
As the result the node<->closure pairs wouldn't be collected until reset the UI and DebuggerPresentationModel.
