 Edward Kmett
 [http://www.haskell.org/pipermail/libraries/2011-November/017152.html
 proposed] to move the instances from `Control.Monad.Instances` to
 `GHC.Base`.

 The deadline of the proposal has passed and no objections were raised.

 The attached patch implements Edward's proposal with a slight
 modification: the instances for `Either` are moved to `Data.Either`.
