[GHC] #2798: Enable "rec" keyword when RecursiveDo is enabled?

[Iavor Diatchki]

Hello,
so with these changes, what is the preferred way to write recursive
monadic code that will work on GHC < 6.12.1, GHC >= 6.12.1, and Hugs?
I guess, one could always fall back to just using "mfix" directly but
this seems unfortunate.
