Log:
        PR c/41049
        * real.c decimal_from_integer, decimal_integer_string): New.
        (real_from_integer): Use them as special case for decimal float.
        * config/dfp-bit.c (_si_to_sd, _usi_to_sd): Use default rounding.
        (_di_to_sd, _di_to_dd, _di_to_td, _udi_to_sd, _udi_to_dd, _udi_to_td):
        Do not append zero after the decimal point in string to convert.
        * dfp/pr41049.c: New test.
