We already know that we need to check whether lcssa phis are supported in inner loop exit block or in outer loop exit block, and we have logic to check them already. Presumably the inner loop latch does not have lcssa phis and there is no code that deals with lcssa phis in the inner loop latch. However, that assumption is not true, when we have loops with more than two-level nesting. This patch adds checks for lcssa phis in the inner latch.
