Subject: [PATCH] Fixed namespace issue for simd-iterator test

The stream output operator<< needed by boost test was in the global namespace where
its presence was ambiguious, which resulted in changes of behaviour across
different compilers. The operator has now been moved into xvec::simd
where it can be found reliably. This only affects testing, not the main
library itself.
