In CardTableModRefBSForCTRS::process_chunk_boundaries() there is a NOISY definition to log some debug messages.

Several problems with this macro:
* The code inside process_chunk_boundaries() is very hard to read due to all the NOISY lines.
* The logging is done to tty and not the logging framework-.
* At some point someone detected a conflict with a preprocessor flag.

It is better to remove this macro and just add relevant logging if we every find the need for it.
