Try moving the top layer flag from ElementRareData to NodeFlags. It may fix the perf regression described in bug 106726, and has been suggested earlier, e.g., https://bugs.webkit.org/show_bug.cgi?id=84796#c31 Moving it to NodeFlags also simplifies some of the code and makes it no longer necessary to allocate rare data.

Doesn't look like it fixed the performance regression. :(
