Alexey Bataev 6f7160eedb [SLP]Attempt to vectorize long stores, if short one failed.

We can try to vectorize long store sequences, if short ones were
unsuccessful because of the non-profitable vectorization. It should not
increase compile time significantly (stores are sorted already,
complexity is n x log n), but vectorize extra code.

Metric: size..text

In all benchmarks extra code gets vectorized
