  * Add rebindable syntax for if-then-else
  
  There are two main changes
  
   * New LANGUAGE option RebindableSyntax, which implies NoImplicitPrelude
  
   * if-the-else becomes rebindable, with function name "ifThenElse"
     (but case expressions are unaffected)
  
  Thanks to Sam Anklesaria for doing most of the work here
