undocumented cost centres with -hd and -hy

When using the heap profiling options -hd (profiling by closure description) and 
-hy (profiling by type) there are some compiler-generated cost centres, for 
example "PAP", "MUT_ARR_PTRS_FROZEN" and "BLACKHOLE". I wasn't able to find 
documentation on them. Is there any?

Thanks,
Sönke
