Improved tests caught a longstanding bug in the compile-time optimization logic for round/roundEven. These would *always* round to an even number even when it didn't make sense to do so. (e.g. 3.1 would round to 4.) RoundEven isn't available in lower shader models of Direct3D; SPIRV-Cross throws if it's unavailable. We may need a caps bit for this.
