Downgrading to P5; this would never be release-critical.
Missing this warning does seem a shame though. And, I think that people who
want this warning would rather have false positives (which can be avoid with
perhaps-unncessary optimizations) than false negatives, which can result in
bugs of exactly the kind they're trying to catch. I'd suggest that we consider
moving this check very early in the optimization chain so that we get more
consistent results across platforms, more consistent results across
optimization levels, and more predictability from release to release.
