title: ReSharper warning for spurious ReSharper comments/attributes?
body: <p>In the course of time and after several refactorings, I often have code littered with spurious and unnecessary <code>ReSharper disable</code> comments and <code>[SuppressMessage("ReSharper", "X")]</code> attributes. As code evolves, what used to be a valuable warning suppression is now not needed.</p>
  
  <p>Is there a way to get ReSharper to warn me when these comments/attributes are no longer needed?</p>
  
  <p>This would be especially useful for unit tests. For example, I'm often invoking the constructor of the class under test without assigning it to any variables, because it's useful to guarantee constructor behavior. So of course I'll put in the <code>// ReSharper disable once ObjectCreationAsStatement</code> comment. But then I'll often find a refactoring that assigns the constructed instance to a variable, and then the comment I put in to disable the warning is no longer needed and just clutters the code.</p>
