Not sure how you want to use it with `vector`, but I'd be fine with making
`constexpr` support a follow-up patch. Given that `vector` is `constexpr` I'd
really like to see the support implemented before adding it to libc++ though,
since it'd require quite a bit of working around non-constexpr support
otherwise.
