On our internal benchmarks it's mostly neutral, but the benchmark that motivated it improved by 5.3%.  We have some extra code, though, that is supposed to deal with similar cases, so some of the impact may be reduced.  By default it keeps the behavior unchanged, so for all other architectures it should have no effect.
