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

Sorry for the delay! Rebased after recent LoopInterchange changes.

There has been a minor change to fix a compilation issue with the test suite: floating point LCSSA phi nodes are not supported, as they currently are the only way to detect FP reductions.

I plan to commit this tomorrow, in case there are no further objections.
