      Expose enabled language extensions to TH · c1e25536
      Ben Gamari authored
      This exposes `template-haskell` functions for querying the language
      extensions which are enabled when compiling a module,
      
      - an `isExtEnabled` function to check whether an extension is enabled
      - an `extsEnabled` function to obtain a full list of enabled extensions
      
      To avoid code duplication this adds a `GHC.LanguageExtensions` module to
      `ghc-boot` and moves `DynFlags.ExtensionFlag` into it. A happy
      consequence of this is that the ungainly `DynFlags` lost around 500
      lines. Moreover, flags corresponding to language extensions are now
      clearly distinguished from other flags due to the `LangExt.*` prefix.
      
      Updates haddock submodule.
