I don't remember. It might just be that trying to create a constexpr 
vector variable or calling __builtin_shuffle on it ICEs instead of giving 
an error. I can keep a note to make some tests at the end of July (I will 
be mostly away until then), but I believe the code from comment 22 is 
safer than the one from comment 20, if memory serves.
