ART: Print and dump functionalities per pass

LOG is a great logging tool but sometimes a pass has some debugging text it
 want to be able to turn on/off easily.

By going via a print_pass flag, we can actually turn it on/off easily per pass
 when debugging/instrumenting.

- Added a pass printer to help debug messages for future passes.
- Added a print_pass flag in CompilationUnit to filter out messages.

At the same time, did a similar system for dumping the CFG.

- Also moved some API into public from protected.
