Bug#850915: ghc: Please switch to llvm 3.8 or, better, 3.9

Hello,

as said, with ghc 8.0.1 and 8.0.2 this seems a little impossible, but as Clint said on debian-haskell

so for Buster we will probably ship 8.2 or something even newer.

But for now, I don't think such change is worth the effort, specially because it will probably introduce
bugs because this will be an untested configuration.
I really hope with 8.2 to make this one disappear :)
(I guess it will be released in some months)
