Hmm... in terms of commit counts, llvm dwarfs clang, and everything else is
in the noise (based on my fading memory of data from two years ago, but still).
I wouldn't think log "pollution" is that big a deal for those doing llvm work.
The inverse problem is that llvm logs would drown out lower-activity
subprojects, but you can get around that with 'git log llvm/tools/clang' or
whatever.
