  [JSC] Check for exception in IntlSegmenter

https://bugs.webkit.org/show_bug.cgi?id=298912
rdar://160595178

Reviewed by Yusuke Suzuki.

The call to jsSubstring can return nullptr on exception in
IntlSegmenter::createSegmentDataObject, which is currently not being checked.

With the addition of DECLARE_THROW_SCOPE in createSegmentDataObject, the
exception checks are covered by the existing stress/intl-segmenter.js test.
