don't update layout for innerHTML	eric: review+

Description Maciej Stachowiak 2007-09-30 02:19:30 PDT

innerHTML updates layout every time it is read. This can be seen on "http://celtickane.com/projects/jsspeed2007.php", where on the DOM test (actually primarily a test of innerHTML) we are currently the slowest of any browser.

I also looked, it appears that createMarkup(Node*... does not actually touch the render tree (renderer()) so I agree, this looks safe.  r=me

Incidentally this patch is a 65% speedup on that one test in the benchmark.
