typeck.c (convert_ieee_real_to_integer): Call fold on the range checking trees as they're being built.

        * typeck.c (convert_ieee_real_to_integer): Call fold on the range
        checking trees as they're being built.
        (convert): Call convert_ieee_real_to_integer if we're
        converting a constant, even if we're writing a class file.
