More work towards cross-compilation
There's now a variant of the Outputable class that knows what
platform we're targetting:
class PlatformOutputable a where
pprPlatform :: Platform -> a -> SDoc
pprPlatformPrec :: Platform -> Rational -> a -> SDoc
and various instances have had to be converted to use that class,
and we pass Platform around accordingly.
