Reviewed by Eric Seidel.

Source/WebCore:

When a node with a wheel or a touch event is moved from one document to
another, the didAddMumble/didRemoveMumble calls do not balance because
they're called on different documents. This patch twiddles the counts
appropriately in that case.

Test: fast/events/move-element-with-wheel-and-touch-event-listeners.html

* dom/EventNames.h:
(WebCore::EventNames::isTouchEventType):
(EventNames):
(WebCore::EventNames::touchEventNames):
* dom/Node.cpp:
(WebCore::Node::didMoveToNewDocument):

LayoutTests:

Test what happens when we move a node with wheel and/or touch events
from one document to another. Prior to this patch, this test triggers
ASSERT(m_wheelEventHandlerCount > 0) in Document.cpp.

* fast/events/move-element-with-wheel-and-touch-event-listeners-expected.txt: Added.
* fast/events/move-element-with-wheel-and-touch-event-listeners.html: Added.
