Update output for TH_exn1
I'm actually not certain why this output has changed: - Code: case reverse "no" of  -> return (GHC.Base.) + Code: let + return = return + $dMonad = Language.Haskell.TH.Syntax.$f22 + in case reverse "no" of  -> return (GHC.Base.) Perhaps it's something to do with inlining? Anyway it's not too important, because this stuff is only displayed for TH splices that crash with (head ) or something like that.
