Remove Enum from Float and Double

There have been several discussions over the years regarding Enum instances
for Float and Double. The conclusion each time appears to have been that
there are no instances which are both sane and practical.

I would like to propose that these instances be removed from Haskell 2014.
This may be covered by the various alternative prelude and number class
proposals, but they are much more ambitious and less likely to make it into
the standard in the short term.
