--------------------------
Deal with NaN and Infinity
--------------------------

This commit arranges that

* GHC.Real exports infinity   :: Rational = 1 :% 0
notANumber :: Rational = 0 :% 0

* GHC.Float.fromRat converts these Rational non-numbers into
  their Float/Double equivalents

As a result, arith015/arith016 start to work again.  We can
read NaN and Infinity into Float/Double.
