[Haskell-cafe] Crossreferenced codebase for Stackage LTS 9.2 available

[Robin Palotai]

Hi Niklas - sounds like a nice usecase.

Though we need to make sure no usages are missing to make that decision
(there are some edge cases yet, for example around TH splice application,
or type families). Also it's only valid on the set of indexed packages.

I'll merge later, but
https://github.com/robinp/haskell-indexer/commit/0592c3d934515c4661c69c5b998e26a543b93b52
has the changes necessary. Note:
- It didn't index ~50 packages
- For some it complained that C libs are missing (like SDL, though I was
using the full stack-build Docker image)
- I had to kill a few huge compilations that ate my RAM (Agda,
language-python, and some yi packages)

I would estimate 8-12 hours, but didn't follow closely (also it was idling
quite some due to the huge compilations).

By the way the per-package entries are available for download in a tarball,
so if you just index your local packages and dump the entries along with
those of your dependencies into the graphstore, you can get a ~full local
index without reexecuting the whole indexing. In the future it would be
nice to have tooling that magically fetches the pre-generated entries you
need, and merges them locally.
