Don't use the threaded HTML parser for javascript: URLs
https://bugs.webkit.org/show_bug.cgi?id=107975

Reviewed by Adam Barth.

Several layout tests depend on javascript: URL iframes loading synchronously including fast/loader/javascript-url-encoding.html.
This patch avoids using the threaded parser for those URLs so they will continue to be synchronous.

No new tests because covered by existing tests.
