createFragmentExpression will fail if it determines that the expression cannot be split over fragments. Handle this case in SROA. Similarly to D147312 <https://reviews.llvm.org/D147312> this should be a rare occurrence as the `dbg.assign` will usually reference the `Value` being stored without modifying it with a `DIExpression`.
