[PATCH] D43237: [LoopInterchange] Allow some loops with PHI nodes in the exit block.

So the problem is specifically with values produced in the loop latch?  That makes sense, I guess, but it seems like you could check for that more directly.  (It might also be possible to hoist the instruction out of the latch, but I guess that's complicated in general.)
