See https://github.com/input-output-hk/nix-tools/pull/101 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).
