  Replace remaining usage of TName with TSymbol
  
  TName used to contain just a subset of the information stored in
  TSymbol. It makes more sense to use TSymbol directly instead of
  converting it to TName.
  
  This also improves type safety a bit by making some functions only
  take in TVariable or TFunction instead of the more generic TName.
