title: UglifyJS - Remove specific functions calls
body: <p>Is there a way to discard calls to specific functions calls using Uglify2?
  Like the option <strong>drop_console</strong> will discard calls to console.* functions. I need to discard calls to specific functions. 
  For example:</p>
  
  <pre><code>var myObj = {
      func1: function() {},
      func2: function() {},
      func3: function() {},
  };
  </code></pre>
  
  <p>Then, remove all <strong>myObj.*</strong> calls. Is this possible?</p>
