core: Fix size_hint for signed integer Range<T> iterators
There was an overflow bug in .size_hint() for signed iterators, which produced an hilariously incorrect size or an overflow panic. Incorrect size is a serious bug since the iterators are marked ExactSizeIterator. (And leads to abort() on (-1i8..127).collect() when the collection tries to preallocate too much). All signed range iterators were affected. > (-1i8..127).size_hint() (18446744073709551488, Some(18446744073709551488)) Bug found using quickcheck. Fixes #24851
