Max Kazantsev 4e5297ed76 [LSR] Fix Shadow IV in case of integer overflow ... When LSR processes code like int accumulator = 0; for (int i = 0; i < N; i++) { accummulator += i; use((double) accummulator); } It may decide to replace integer `accumulator` with a double Shadow IV to get rid of casts. The problem with that is that the `accumulator`'s value may overflow. Starting from this moment, the behavior of integer and double accumulators will differ. This patch strenghtens up the conditions of Shadow IV mechanism applicability. We only allow it for IVs that are proved to be `AddRec`s with `nsw`/`nuw` flag.
