  Performs the following context-free rewritings:

  - Places all pattern variables in Bind nodes. In a pattern, for identifiers `x`:

                      x  => x @ _
                    x:T  => x @ (_ : T)

  - Removes pattern definitions (PatDef's) as follows: If pattern is a simple (typed) identifier:

               val x = e     ==>  val x = e
               val x: T = e  ==>  val x: T = e

  if there are no variables in pattern

             val p = e  ==>  e match (case p => ())

  if there is exactly one variable in pattern

             val x_1 = e match (case p => (x_1))

  if there is more than one variable in pattern

             val p = e  ==>  private synthetic val t$ = e match (case p => (x_1, ..., x_N))
                             val x_1 = t$._1
                             ...
                             val x_N = t$._N

  - Removes function types as follows:

             (argtpes) => restpe   ==>   scala.Function_n[argtpes, restpe]

  - Wraps naked case definitions in a match as follows:

             { cases }   ==>   (x => x.match {cases}), except when already argument to match
