I've uploaded the revised patch. And add comments on bugzilla to ChangeLog.

>> Source/WebCore/cssjit/SelectorCompiler.cpp:610
>> +static inline BacktrackingAction solveTraversalBacktrackingAction(const SelectorFragment& fragment, bool hasDescendantRelationOnTheRight)
> This is only for adjacent backtracking action, let's name this solveAdjacentTraversalBacktrackingAction() for clarity.

That's reasonable. I've renamed it.

>> LayoutTests/fast/selectors/backtracking-adjacent.html:113
>> +description('The backtracking direct adjacent combinator with descendant tail cases');
> Hum, I am confused here, none of the cases tested needs a descendant tail.
> I think what would make a good test here is cases of adjacent chain inside a descendant chain where a descendant tail would have been needed before your backtracking optimizations.

Right. I've changed this with 'The backtracking from adjacent combinators'.

And added test cases using backtracking tails.
