Should this be guarded instead by ENABLE_TOUCH_EVENTS

Because hasTouchEventListener() is only in iOS. And the function body of dispatchedTouchEvent() is guarded by IOS_TOUCH_EVENTS. Do you think I should change it to IOS_TOUCH_EVENTS?

Is this changing the behavior of both createPlatformTouchEvent and createPlatformSimulatedTouchEvent? Is that desired?

This only affects createPlatformSimulatedTouchEvent.

Test seemed to be timing out. I think we don't need to do the async test.

Don't forget that touch event code in OpenSource is different (and mostly disabled).

Is there a way to test code that's guarded by IOS_TOUCH_EVENTS with a layout test?
