Extend CFGPrinter and CallPrinter with Heat Colors: Polly changes

[rcorcs]

Summary

This patch has the necessary changes to Polly in order to support the new CFGPrinter with Profiling Heat Colors.

Reference to the Heat Color patch: https://reviews.llvm.org/rL336000

Thanks! However, I am a little confused: when do I merge this, precisely? It breaks on current LLVM HEAD.

[rcorcs]

It will need to be synchronised with the merge of the other patch.
Otherwise, the other patch would break Polly.

[bollu]

So, how do we coordinate this? :) Or do you push the patches at the same time?
