Have preloader handle crossorigin resources better.

Have preloader handle crossorigin resources better.

Make the preloading of resources understand CORS better:

 - correctly interpret a 'crossorigin' attribute without a value
   as "anonymous".
 - enable a CORS fetch if the attribute was present. For <script>
   and <img>, currently.

Retried try job too often on win_blink_rel for step(s) webkit_tests
http://build.chromium.org/p/tryserver.chromium/buildstatus?builder=win_blink_...

Retries on win_blink_rel appears unrelated, so will try again.

However, noticed that one field was left uninitialized in the HTMLPreloadScanner
constructor. Unintentional, albeit harmless right now. Added the initialization
though.
