Fix floating point bug in fold_range.
We currently do not have any floating point operators where operand 1 is
a different type than the LHS. When we eventually do there is a bug
in fold_range. If either operand is a known NAN, it returns a NAN
of the type of operand 1 instead of the result type.
* range-op-float.cc (range_operator_float::fold_range): Return
NAN of the result type.
