patch applied (ghc): Breakpoint code instrumentation

Sun Dec 10 12:49:34 PST 2006  Pepe Iborra <[email protected]>
  * Breakpoint code instrumentation
  
  Instrumentation gets activated by the '-fdebugging' dynflag.
  
  All the instrumentation occurrs in the desugarer; it consists of inserting 'breakpoint' combinators at a number of places in the AST, namely: 
   - Binding sites
   - Do-notation statements 
  These 'breakpoint' combinators will later be further desugared (at DsExpr) into ___Jump functions.
  For more info about this and all the ghci.debugger see the page at the GHC wiki:
