[PATCH] D21665: [LoopSimplify] Update LCSSA after separating nested loops.

Hi Sanjoy,

Thanks for review! You're right that we need to look not only at `NewBB` but in other blocks that happen to be outside the inner loop as well. I updated the test to check this case as well.

Also, I decided to make `processInstruction` from `LCSSA` externally available, since it greatly simplifies the patch. I'll submit the corresponding patch for a separate review (we'll need to iron out the API we want to have there), but I'll keep it here as well just to show you the complete picture.

Thanks,
Michael
