Noissue - Check domains first for regular expression filters

Following up on https://hg.adblockplus.org/adblockpluscore/rev/3ab884752712

Sebastian points out that sometimes there can be domain-specific regular expression filters that are too complex and cause the browser to hang. It is for this reason that the document's domain was being checked before the request URL.

This patch is a compromise where we have the best of both: for regular expression filters we check the document's domain first (safety), for other filters we check the request URL first (performance).

Performance is OK with this.
