Hello,

VECTOR_TYPE should be a literal type in C++11, so we can have for instance:
constexpr __m128i v = { 1, 0 };
constexpr __m128i s = v + v;

Once PR c++/51033 is fixed, ideally, the following would also work:
constexpr long long i = v[1];
constexpr __m128i w = __builtin_shuffle (m, m);

but I guess this can be made in several steps as long as the compiler doesn't
ICE on those.
