Jeffrey Walton	6e829cebee	Use EPI8 Shuffle rather than Shifts and Or for rotate when R=8 Louis Wingers and Bryan Weeks from the Simon and Speck team offered the suggestion. The change save 0.7 cpb for Speck, and 5 cpb for Simon on x86_64. Speck is now running very close to the Team's time sor SSE4. Simon is still off, but we know the root cause. For Simon, the Team used a fast bit-sliced implementation	2017-11-29 08:53:48 -05:00
