Comment (by ulysses4ever):

 Actually, I don't see `thNameToGhcName` used anywhere (on master). So it
 could be (relatively) freely moved. Maybe `TcSplice`, which it depends
 upon, is the right place for it? In that case the return type's monad,
 probably, should be changed from `CoreM` to plain `IO`.
