LGTM, thank you!

Does this warrant a release note, as it is changing the behavior in a backwards-incompatible manner? I do think changing to match GCC is worthwhile, even if it means a change in behavior for Clang.

I also don't think the "longest first" heuristic is useful enough to outweigh the benefits of behaving like GCC; it seems like the user can always sort their own options to get the same effect.
