// Check that all combinations of alignment, frame offset and chunk size work
// correctly for MaskWebSocketFramePayload(). This is mainly used to ensure that
// vectorisation optimisations don't break anything. We could take a "white box"
// approach and only test the edge cases, but since the exhaustive "black box"
// approach runs in acceptable time, we don't have to take the risk of being
// clever.
//
// This brute-force approach runs in O(N^3) time where N is the size of the
// maximum vector size we want to test again. This might need reconsidering if
// MaskWebSocketFramePayload() is ever optimised for a dedicated vector
// architecture.
