Sorting small arrays is a relatively common problem in GPGPU programming. Many useful algorithms exist, and some are provided by libraries like CUB. An algorithm close to my heart is odd-even sort because it is exceedingly simply, relatively efficient for small arrays and, importantly, it uses O(1) space. This commit adds new implementations of this sorting algorithm for block-wide odd-even sort in a portable way.
