Source/WebCore:

When traversing with the indirect adjacent combinator, SelectorChecker
was not setting the style invalidation flag on the right element.

Tests: fast/css/indirect-adjacent-style-invalidation-1.html

LayoutTests:

There are multiple variations of the same tests to test
cases where we JIT and cases without JIT.
