-;                |
-;                v
-;         ( outer.header ) <--

-;  ( inner.latch )   ( outer.latch )
-;         |
-;         v
-;     ( exit )
-;
-; When the inner loop is unrolled, we inner.latch block has only one
-; predecessor and one successor, so it can be merged with exit block.
-; During the merge, however, we remove an LCSSA definition for
-; %storemerge1.lcssa, breaking LCSSA form for the outer loop.

-; This case is similar to the previous one, and has the same CFG.
-; The difference is that loop unrolling doesn't remove any LCSSA definition,
-; yet breaks LCSSA form for the outer loop. It happens because before unrolling
-; block inner.latch was inside outer loop (and consequently, didn't require
-; LCSSA definition for %x), but after unrolling it occurs out of the outer
-; loop, so we need to insert an LCSSA definition to keep LCSSA.
