Extends the CFGPrinter and CallPrinter with heat colors based on heuristics or profiling information.

This patch was firstly published by Rodrigo Caetano Rocha (@rcorcs) on 11/24/17. After several rounds of reviews, it was deployed, but, mainly due to the conflict with Polly, it was reverted. After that, the conflict with Polly alongside some other small issues was fixed, but never deployed. The diff then was closed due to the commit that probably happened during migration. I would like to bring this change upstream. I have taken it up to me to make some changes regarding flags initialization and refactoring some older tests to match the new output of CFGPrinter specifically. All the further info on the patch you can find in the previous reviews.
