title: webpack html-webpack-plugin, can I use conditional comments to import entry script?
body: <p>I have multiple entry like:</p>
  
  <pre><code>entry: {
    foo: 'foo.js'
    bar: 'bar.js'
    ie: 'ie.js'
  },
  output: {
    path: path.join(__dirname, '/dist/'),
    filename: '[name]-[hash].min.js'
  }
  </code></pre>
  
  <p>when I use HtmlWebpackPlugin, It's for certain to import or not import an entry, using chunks.
  I hope to generate conditional comments in HTML file, like:</p>
  
  <pre><code>&lt;!--[if lte IE 9]&gt;
    &lt;script type="text/javascript" src="ie-12dx....js"&gt;&lt;/script&gt;
  &lt;![endif]--&gt;
  </code></pre>
  
  <p>Any idea on how to achieve that?</p>
