L. David Baron 133a7fac65 Bug 977991 patch 1 - Expose variant of RulesMatching on nsHTMLCSSStyleSheet that is less work to call. r=birtles
This allows nsStyleSet::RuleNodeWithReplacement to call it without
constructing an entire (and unnecessary) ElementRuleProcessorData, which
will happen in patch 3.
