• fix ​http://bugs.webkit.org/show_bug.cgi?id=14742 Document::recalcStyle(Force) called for every updateStyleIgnorePendingStylesheets while waiting for stylesheets <rdar://problem/5376306>

updateStyleSelector() is normally called when something changes that factors
into the style selector. However, updateLayoutIgnorePendingStylesheets() calls it for
a different reason, namely to account for all the preceding changes that were ignored
because of the early return in updateStyleSelector(). After that, the early return
can no longer occur, so changes are accounted for as they happen, and
updateLayoutIgnorePendingStylesheets() does not need to call updateStyleSelector()
again.

• dom/Document.cpp: (WebCore::Document::updateLayoutIgnorePendingStylesheets): Call updateStyleSelector() only before the first layout.
