Add missing float fold_range prototype for floats.
Unary operations require op2 to be the range of the type of the LHS.
This is so the type for the LHS can be properly set.
* range-op-float.cc (range_operator_float::fold_range): New base
method for "int = float op int".
* range-op.cc (range_op_handler::fold_range): New case.
* range-op.h: Update prototypes.
