It seems better to do the following, so we still test for extra warnings:

-template <class T> void g (T) {}

-template <class T> auto g (T x) -> typename enable_if<sizeof(__builtin_shuffle(x,x))!=2>::type {}

+template <class T> void g (T const&) {}

+template <class T> auto g (T const& x) -> typename enable_if<sizeof(__builtin_shuffle(x,x))!=2>::type {}

I committed that as an obvious fix of my testcase.
