-; This test contains a carefully rotated set of three nested loops. The middle
-; loop can be unrolled leaving one copy of the inner loop inside the outer
-; loop. Because of how LICM works, when this middle loop is unrolled and
-; removed, its alias set tracker is destroyed and no longer available when LICM
-; runs on the outer loop.
