Masayuki Nakano b4cc4486d4 Bug 1449831 - part 1: Add InputEvent.getTargetRanges() r=smaug
`InputEvent.getTargetRanges()` can be used only when event type is
`beforeinput`.  So, it may be used for feature detection of `beforeinput`
event because Chrome does not implement `onbeforeinput` event handler attribute.
Therefore, this patch makes it behind the pref for `beforeinput` event.
