ART: Save work-line for pending runtime failure

When we detect a pending runtime failure, we'll handle it as a
generic throw, no matter the instruction type. But we won't have
saved the work-line, which means we'll try to merge garbage into
the handler's line.

Copy the work-line when we set the failure.
