Add the initial implementation of dynamic specificity for :matches() https://bugs.webkit.org/show_bug.cgi?id=138822 Reviewed by Andreas Kling. Source/WebCore: Previously we completely ignored the selector list of :matches() when computing the specificity of the selector. The spec (http://dev.w3.org/csswg/selectors4/#specificity) says: "The specificity of a :matches() pseudo-class, however, is the specificity of the most specific complex selector that matched the given element." This patch does just that. In the CSS JIT, we only consider specificities that can be computed statically for now, this should be extended later. When the specificity is dynamic, we fall back to SelectorChecker. In that case, we execute every selector of the selector list and we keep the maximum value as the specificity for the whole :matches().

The specificity of its components is computed in SelectorChecker. Since :matches() is no longer accounted as a class B specificity, I had to finish the specificity of :not() or some test breaks. * css/CSSSelector.h: * css/PageRuleCollector.cpp: (WebCore::comparePageRules): * css/SelectorChecker.cpp: (WebCore::SelectorChecker::checkOne): We can no longer shortcut the execution when context.pseudoElementEffective is false. There is no guarantee that a following selector wouldn't match with a higher specificity. * cssjit/SelectorCompiler.cpp: (WebCore::SelectorCompiler::addPseudoClassType): (WebCore::SelectorCompiler::SelectorCodeGenerator::SelectorCodeGenerator): (WebCore::SelectorCompiler::constructFragments): (WebCore::SelectorCompiler::SelectorCodeGenerator::generateSelectorChecker): LayoutTests: * fast/css/matches-specificity-1-expected.html: Added. * fast/css/matches-specificity-1.html: Added. * fast/css/matches-specificity-2-expected.html: Added. * fast/css/matches-specificity-2.html: Added. * fast/css/matches-specificity-3-expected.html: Added. * fast/css/matches-specificity-3.html: Added. * fast/css/matches-specificity-4-expected.html: Added. * fast/css/matches-specificity-4.html: Added. * fast/css/matches-specificity-5-expected.html: Added. * fast/css/matches-specificity-5.html: Added. * fast/css/matches-specificity-6-expected.html: Added. * fast/css/matches-specificity-6.html: Added. * fast/css/matches-specificity-7-expected.html: Added. * fast/css/matches-specificity-7.html: Added. * fast/css/matches-specificity-8-expected.html: Added. * fast/css/matches-specificity-8.html: Added. * fast/css/matches-specificity-9-expected.html: Added. * fast/css/matches-specificity-9.html: Added. * fast/css/matches-specificity-10-expected.html: Added. * fast/css/matches-specificity-10.html: Added.
