IDL: remove force rebuild comments from 'implements', as bug fixed

Comments of the form:
// force rebuild: crbug.com/307023
were added to a few IDL files due to bug 307023
(implements dependencies not being handled by the build)

This has now been fixed, so they can be removed.

Keep frames to navigate alive in HistoryController::goToEntry()

Otherwise, if a script executed during the navigation of one frame (for
instance a popstate event handler) removes other frames from the document,
the calls to navigate those frames later on are given pointers to dead
objects.

This patch makes the more localized fix committed as r165081 redundant,
and thus reverts it from FrameLoader::loadHistoryItem().
