Serguei Katkov 00cc875c77 [LoopInfo] Fix getUniqueNonLatchExitBlocks ... It is possible that exit block has two predecessors and one of them is a latch block while another is not. Current algorithm is based on the assumption that all exits are dedicated and therefore we can check only first predecessor of loop exit to find all unique exits. However if we do not consider latch block and it is first predecessor of some exit then this exit will be found. Regression test is added. As a side effect of algorithm re-writing, the restriction that all exits are dedicated is eliminated.
