Comment(by simonpj):

 Thanks for the patches.  They look right to me.  Except that don't you
 need something in `TcSplice`, where we make `TcM` an instance of `Quasi`
 to give the appropriate instance for `qAddDependentFile`?

 Ian will commit, but first.... Template Haskell is '''greviously'''
 lacking in documentation.  The right place to document the new operation
 is in the Haddock docs; current snapshot is
 here:http://www.haskell.org/ghc/dist/current/docs/html/libraries/template-
 haskell-2.6.0.0/Language-Haskell-TH.html

 Could you add documentation for your new operation, and for any others you
 feel moved to document; `report`, `recover`, `reifyInstances`,
 `isInstance` seem prime candidates, but you may have other ideas too.

 Many thanks

 Simon
