ghc-gc-tune: Missing fields in GC stats

[flip111]

Hello,

I saw that you got the source code for ghc-gc-tune. I don't know where you got it because the original link seems dead http://code.haskell.org/~dons/code/ghc-gc-tune

Anyway since i didn't find a location to report bugs only here, i will report a bug here. I'm on stack lts-13.14 and i get:
