voila!

Now the question is whether to bother fixing this:
1. in GCC 8's rs6000/emmintrin.h, since it's not really "broken" there, and
backport that AT 11 (sounds a little silly)
2. backport the GCC 8 change that fixes this to AT 11 (sounds hard)
3. change only AT 11's emmintrin.h
Any strong opinions? Otherwise, I'm leaning toward option (3).
