We should look up hsPkgs.${pkg-name}.components.exe.${component-name}
instead of including the package as a dependency.
Adding `hsPkgs.${pkg-name}` a tool it is not clear which executable in the package `haskell.nix` should choose.
Haskell.nix did not deal with this well and in fact it could lead to `nix-shell` crashing. For instance using `shellFor` to make a shell for building `haskell-language-server` with `cabal build` crashed as a dependency on `ghcide` the executable (by the `ghcide-bench` executable) caused infinite recursion. Allowing `ghcide-bench` to correctly depend just on `components.exes.ghcide` fixes this.
This PR also includes:
* Updated materialized files built with the new nix-tools and latest index-state
* Small update to GHCJS (pins happy) to fix issue that showed up when the materialization was updated
* A fix for the infinite recursion issue when updating materialized files (by adding ghc-boot-packages-unchecked).
* Performance fix for shellFor (checks just the names of component derivations when filtering).
* Update default nixpkgs to 20.09
* Move more CI to work on 20.09 by default
* IFD level 1
* Use nixpkgs 20.03 emscripten (needed for ghcjs)
* Add missing materialized files
* Add missing materialized files
* Fix for ghc 8.8 build on darwin
* Fix for ghcjs 8.8 build on darwin
* Fix hls stack test eval for ghc810220201118
* ifdLevel 2
* Oops: accidentally turned on tests for experimental GHC
* Revert "Fix hls stack test eval for ghc810220201118"
This reverts commit b405cd7ee8bd62214bd2d0a61e0317673b5bf1b5.
* ifdLevel 3
* Disable GHC 8.6.5 windows cross on nixpkgs 20.09
* Update supported GHC doc with a table

This change introduces a `ghc8102-experimental` compiler-nix-name that behaves much like the `ghc8102` version but includes @JoshMeredith's patch `./patches/ghc/ghc-8.10-ubxt.patch` that writes the `cg_binds` field with:
```haskell
liftIO $ registerInterfaceDataWith "ghc/phase/core" hsc_env $ \bh ->
putWithUserData (const $ return ()) bh (map toIfaceBind $ cg_binds cg_guts)
```
Some of the places where we used to depend on the output of `plan-to-nix` containing the correct `nix-name` for the compiler have been update to avoid using incompatible interface files from the `compiler-nix-name = "ghc8102"` version of GHC.
It looks like we can't use 8.8 for booting due to
https://gitlab.haskell.org/ghc/ghc/-/issues/18143
* Adds nixpkgs 20.09 to get mingw-w64 version 6
(also needed for ghc 8.10 windows cross compile)
* Add materialization for ghc 8.10.2 windows cross
* Fix issue with harfbuzz override so it works with nixpkgs 20.09
* Fixes eval time issue for windows index-state test (turns off native-dns cabal flag for windows)
* Include exe extension for windows in coverage test
lib:ghc is still broken for ghc 8.10 (all variants), but it always has been and we should try to fix it properly, but it will be very tricky.
Changes to the interface of haskell.nix (from the changelog.md file):
* Removed `sources.nixpkgs-default`, use `sources.nixpkgs` instead.
* Removed `./nixpkgs` directory, use `(import ./. {}).sources`
or `./nix/sources.nix` instead.
* Removes V1 interface for details on how to fix old code see:
https://github.com/input-output-hk/haskell.nix/issues/709
* Removed defaultCompilerNixName.
* cabalProject, cabalProject', hackage-project and hackage-package
now require a `compiler-nix-name` argument.
* `haskell-nix.tool` and `.tools` now require a `compiler-nix-name` argument.
New functions `p.tool` and `p.tools` (where p is a project) do not.
Like `shellFor { tools = ... }` they will use the compiler nix name
from the project (including stack projects where it is derived from
the resolver).
* `haskell-nix.alex` and `haskell-nix.happy` have been removed. Use
`p.tool "alex" "3.2.5"` or `shellFor { tools = { alex = "3.2.5"; } }`.
* `haskell-nix.nix-tools` -> `haskell-nix.nix-tools.ghc883` (it includes
the hpack exe now).
* `haskell-nix.cabal-install` ->
`p.tool "cabal" "3.2.0.0"` or `shellFor { tools = { cabal = "3.2.0.0"; } }`
* `haskell-nix.haskellNixRoots` -> `haskell-nix.roots ghc883` or `p.roots`
Other changes:
Adds hpack executable to the nix-tools derivations.
Adds a `cabal-hpack` test to make sure `hpack` works with
`cabalProject`.
Reduces the number of calls to `cabalProject` (particularly when
checking materialization), by giving internal tools a per-compiler
attribute.
Uses happy 1.19.12 when building newer ghc versions.
Updates cabal-install 3.2.0.0 to use the source from github that
is compatible with ghc 8.10.1.
Updates the docs for callCabalProjectToNix.
Adds a license mapping to fix a common warning.
* ghc 8.10
* Adds/Updates/Removes materialization files
* Disable one-shot-kqueue-on-macos patch on ghc-8.10
* Test ghc883 and ghc8101 but only with nix 20.03
* Various smaller fixes.
This should fix the infinite recursion issue with #654
