Make pattern synonyms work with Template Haskell

Template Haskell has no support for pattern synonyms. This should be added.

Specifically:

  • Create syntax in Language.Haskell.TH.Syntax and corresponding functions in Language.Haskell.TH.Lib
  • Support in !DsMeta for desugaring pattern synonym quotations. See rep_bind.
  • Support in Convert for splicing in pattern synonyms.
  • Support in !TcSplice for reifying pattern synonyms. See reifyThing.
