Re-export GHC.Utils.Panic.Plain from GHC.Utils.Panic
It seems odd having to additionally import the plain panics module when the non-plain one is already in scope.
Some of the bindings are already explicitly re-exported. But I think we should just re-export GHC.Utils.Panic.Plain
wholesale.
Personally I don't see any downsides but others might disagree, hence this ticket.
