simdpp::shuffle2x2

template<unsigned s0, unsigned s1, unsigned N, class E1, class E2> Ret<N,_DETAIL_> shuffle2x2( const Vec1<N,E1>& a, const Vec2<N,E2& b );

Shuffles two vectors at 2x2 element block granularity.

The implementation behaves as if the following set of overloads is provided:

`Ret`	`Vec1`	`Vec2`
promoted 32-bit vector	any 32-bit vector	any 32-bit vector
promoted 64-bit vector	any 64-bit vector	any 64-bit vector

The type of the return vector is governed by the expression promotion rules. The return type is a vector expression.

The selectors s0 and s1 must be in range [0..3].

The vectors are shuffled at 2x2 block granularity as follows: the vectors are partitioned into N/2 groups. The n-th group in the return vector will contain:

elements only from n-th groups of a and b vectors
the first and second elements are selected by the s0 and s1 selectors respectively
values 0 and 1 correspond to the 0 and 1 elements from n-th group from a, 2 and 3 correspond to the 0 and 1 elements from n-th group from b.
