  * Refactor the command-line argument parsing (again)
  
  This change allows the client of CmdLineParser a bit more flexibility,
  by giving him an arbitrary computation (not just a deprecation
  message) for each flag.  
  
  There are several clients, so there are lots of boilerplate changes.
  
  Immediate motivation: if RTS is not profiled, we want to make 
  Template Haskell illegal.  That wasn't with the old setup.

    M ./compiler/main/CmdLineParser.hs -60 +109

    M ./compiler/main/HscMain.lhs +5
    M ./compiler/main/StaticFlagParser.hs -30 +43
    M ./ghc/Main.hs -23 +4
