sort components of vector types

is there any hard implemented instruction for this?

The title says all, is there any sort instruction for vector types (e.g., int4, int8, int16) to sort its components? As I use a great number of vectors of dimensions like 4, 8, 16 (each vector being treated in a work-item), I was wondering if, for example, sorting an int16 vector variable using hardware implemented instructions wouldn't be faster than sorting an array of scalar type (int array[16]) in a single thread (work-item) using algorithms like qsort. If not, would it have a low cost implementation, or even, would it worth try?
