Capturing an IRC conversation:

> **EricWF** jlebar: Did you test this patch with older Clangs w/o constexpr builtins?
>  **jlebar** EricWF, Do you mean, did I test the test, or did I test that the non-test change does what I need?
>  **EricWF** jlebar: I'm wondering if older clangs emit a never-constexpr diagnostic if the builtin isn't > constexpr.
>  **jlebar** EricWF, clang 3.3 and earlier do.
>  **EricWF** OK then we're good :-)

Thank you again for the comments; submitting now with the fixes above.
