Make use of vec<T, N> vector broadcasts

Also disable the assignment operator implicitly doing a broadcast.
Instead the explicit constructor must be used. This prevents bugs like
assigning a scalar to one element, while it was intended to broadcast
(especially when using [] on an array of vectors).
