code: static ConstantFloatInfo make(ConstantPool cp, float value) {
          ConstantInfo ci = new ConstantFloatInfo(value);
          return (ConstantFloatInfo)cp.addConstant(ci);
      }
docs: Will return either a new ConstantFloatInfo object or one already in
  the constant pool. If it is a new ConstantFloatInfo, it will be
  inserted into the pool.
