Stop the deprecation of Data.Monoid.{First,Last}

[Keith]

Apropos of this, can we get flexible instances for Compose? 

It seems like there's some agreement that ignoring the composition is the most useful way to generate fully saturated instances (since requiring e.g. 'composition of a monoid with semigroup' is more useful than 'composition of a monoid with a monoid').
