After thinking a bit more about it, I feel the blacklist should 
go into the repo that contains the functions it is blacklisting. 
That way, the codefix+blacklist-removal  (or code annotation and 
blacklist update from unchecked section to checked) happens in 
one commit, instead of two commits in different repos.

Indeed, I also expect that eventually there shouldn't be any 
blacklist necessary for Phobos code. So then we'll just remove it.

(btw, I think this should be upstreamed at some point; druntime 
and Phobos upstream should have permanent ASan testing upstream 
too)
