------- Additional Comments from Nate Chapin <japhet at chromium.org>
Differences from r137333:

* clearResource() is called in MainResourceLoader's destructor, so we don't
leak m_resource
* No modifications to http/tests/inspector/resource-parameters.html
* Fragment identifier reconstruction is no longer necessary at the end of
MainResourceLoader::load().

Note that until bug 104721 lands, http/tests/inspector/resource-parameters.html
will fail, so EWS for this patch is not excepted to be 100% green.
