> So these functions are specifically added to WTF to provide hook-points for Valgrind, is that correct?

Yes. These are annotations for dynamic tools like Valgrind.

Currently we added them only to thread-safe reference counters (wtf/ThreadSafeRefCounted.h) and strings (wtf/text/StringStatics.cpp, in order to deal with shared string bodies).
