What I was trying to say is that __m128 is defined as:
typedef float __m128 __attribute__ ((__vector_size__ (16), __may_alias__));

Which means there is already an operator+ defined which is done using the
generic GNU vector support.  If you remove your definition of operator+, it
works without it.
