compiler-nix-name = "ghc945" causes Hadrian build failures

[JackKelly-Bellroy]

Describe the bug

The attached tarball fails to build Hadrian with compiler-nix-name = "ghc945", failing with the following error:

src/Hadrian/Haskell/Cabal/Parse.hs:319:26: error: [GHC-76037]
    Not in scope: ‘C.readHookedBuildInfo’
    NB: neither ‘Distribution.Simple’, ‘Distribution.Simple.Build’,
                ‘Distribution.Simple.Compiler’, ‘Distribution.Simple.Configure’,
                ‘Distribution.Simple.PackageIndex’,
                ‘Distribution.Simple.Program.Builtin’,
                ‘Distribution.Simple.Program.Db’,
                ‘Distribution.Simple.Program.Types’, ‘Distribution.Simple.Utils’,
                ‘Distribution.Types.ComponentLocalBuildInfo’,
                ‘Distribution.Types.LocalBuildInfo’, ‘Distribution.Verbosity’,
                ‘Distribution.ModuleName’, ‘Distribution.Package’,
                ‘Distribution.PackageDescription’,
                ‘Distribution.PackageDescription.Configuration’,
                ‘Distribution.PackageDescription.Parsec’, ‘Distribution.Text’,
                ‘Distribution.Types.MungedPackageId’,
                ‘Distribution.Utils.Path’ nor ‘Distribution.Utils.ShortText’ export ‘readHookedBuildInfo’.
    Suggested fix:
      Perhaps use one of these:
        ‘C.emptyHookedBuildInfo’ (imported from Distribution.PackageDescription),
        ‘C.parseHookedBuildInfo’ (imported from Distribution.PackageDescription.Parsec)
    |
319 |         Just infoFile -> C.readHookedBuildInfo C.silent infoFile
    |                          ^^^^^^^^^^^^^^^^^^^^^

Steps To Reproduce

Download the attached
ghc-945-failure.tar.gz, unpack it, and run nix build -L inside. Observe the error.

Expected behavior

I expect it to successfully build Hadrian, and then compile GHC 9.4.5 using it.

Additional context

I bisected the master branch from a commit I knew worked with GHC 9.4.5, and found that f4cdb22 (PR #2088) is the first bad commit. I haven't been able to dig into the PR branch itself.

Should be fixed by #2095
