Reviewed by Antonio Gomes.

.:

Add a manual test for this issue because DumpRenderTree
currently cannot send a group of touch points with
different touch states in one shot.

* ManualTests/resources/iframe-reloaded-on-touch.html: Added.
* ManualTests/touch-stale-iframe-crash.html: Added.

Source/WebCore:

Always perform sanity checks when handling every touch point
because the node and document may have been destroyed or detached.

ManualTests/touch-stale-iframe-crash.html added.
(DumpRenderTree doesn't support transiting touch states in one shot yet)

* page/EventHandler.cpp:
(WebCore::EventHandler::handleTouchEvent):
