`mkDumpDoc` is not exported in GHC 9.0.1
In earlier versions of GHC, the function
mkDumpDoc is exported from the module
ErrUtils. Now, in ghc-9.0.1 this module has been renamed to
GHC.Utils.Err and it stopped exporting the function. We use this function in the fusion-plugin package to print some behind the scenes plugin information.
Can this function be exported again?
