* Source/WebCore/cssjit/SelectorCompiler.cpp:
(WebCore::SelectorCompiler::addPseudoElementPseudoClassType):

This function just return false because ::pseudo-element:pseudo-class case is (per comments) not handled by the compiler at the moment.

(WebCore::SelectorCompiler::constructFragmentsInternal):

Remove the isScrollbarPseudoElement test. It is not needed, only valid selectors are allowed by the parser.
Newly enabled pseudo-elements either conceptually always match or are only tested against elements that match (WebKitCustom pseudos).
Remove the default case so these stay better up to date.

(WebCore::SelectorCompiler::addScrollbarPseudoClassType): Deleted.
(WebCore::SelectorCompiler::isScrollbarPseudoElement): Deleted.
