[PPCGCodeGeneration] Teach Polly to start using live range reordering.
Polly did not use PPCG's live range reordering feature. Teach
PPCGCodeGeneration to use this.
Documentation on this is sparse, so much of the code is conservative.
We currently kill all phi nodes in a Scop by appending them to the
must_kill map we pass to PPCG. I do not have a proof of correctness,
but it seems to be intuitively correct.
We also do not handle `array_order`, which, quoting PPCG, is:
PPCG/gpu.h: "Order dependences on non-scalars."
It seems to consist of RAW dependences between arrays. We need to
pass this information for more complex privatization cases.
