Change LLVM versions for ghc-8.6 to LLVM 6 (#385)

Browse Source 
The LLVM versions specified for the ghc-8.6 series compilers in overlays/bootstrap.nix was LLVM 5, but these compilers state on the download page that they require LLVM 6. This resulted in a warning about a wrong LLVM version for every module compiled with the LLVM backend (e,g, when cross-compiling.) This PR updates the LLVM versions for these compilers to LLVM 6.

Note: ghc-8.8.1 (and presumably future ghcs in the 8.8 series) requires LLVM 7. However it appears haskell.nix does not yet support ghc-8.8.1.

This file contains a summary of changes to Haskell.nix and `nix-tools`
that will impact users.
## December 27, 2019
* Fix overlays/bootstrap.nix to provide LLVM 6, not LLVM 5, to ghc-8.6.X compilers.
## November 18, 2019
* Changed the `cleanSourceHaskell` to accept an attrset of `src` and
(optional) `name` parameters. This allows you to keep the source
