[PATCH] D45728: [Polly] Allow arbitrary function calls for debugging purposes.

[Johannes Doerfert via llvm-commits]

I think it was actually not exactly the same but the early error block
support looked similar. It was replaced by the current error block
handling. What you want is different and seems useful.

With proper/sound I mean approximated dependences for the calls. That
effectivelly prevents optimizations and therefore is not what you want but
similar as it allows calls.

Cheers,
  Johannes
