template<unsigned N, class E1>
Ret reduce_add( const Vec1<N,E1>& a );
Computes the sum of all elements in the vector. The implementation behaves as if the following set of overloads is provided:
The order in which the operations are executed is undefined, but is consistent on the same instruction set. This may lead to slightly different results on different instruction sets due to different rounding.
A sum of all elements within a vector
r = a0 + ... + aN
