Remove Profile Mode, deprecated since GCC 7.1
The Profile Mode extension is not used by anybody, nor maintained by anybody. The containers do not support the full API specified in recent standards, and so enabling Profile Mode is not source compatible with much modern C++ code. The heuristics that would check the profile information and make useful suggestions never materialized, so it isn't useful. It should be removed.
