    Fortran: Fix -freal-{4,8}-real* handling [PR99355]

    Avoid chain kind conversion for, e.g., -freal-4-real-8 -freal-8-real-10.
    Note that gfc_default_double_kind/gfc_default_double_kind already
    honors the -freal flags.

    gcc/fortran/ChangeLog:

            PR fortran/99355
            * decl.c (gfc_match_old_kind_spec, gfc_match_kind_spec): Avoid
            redoing kind conversions.
            * primary.c (match_real_constant): Likewise.
