    Fortran: fix treatment of character, value, optional dummy arguments
[PR107444]

    Fix handling of character dummy arguments that have the optional+value
    attribute.  Change name of internal symbols that carry the hidden prese=
nce
    status of optional arguments to distinguish them from the internal hidd=
en
    character length.  Update documentation to clarify the gfortran ABI.

    gcc/fortran/ChangeLog:

            PR fortran/107444
            * trans-decl.cc (create_function_arglist): Extend presence stat=
us
            to all intrinsic types, and change prefix of internal symbol to
'.'.
            * trans-expr.cc (gfc_conv_expr_present): Align to changes in
            create_function_arglist.
            (gfc_conv_procedure_call): Fix generation of procedure arguments
for
            the case of character dummy arguments with optional+value
attribute.
            * trans-types.cc (gfc_get_function_type): Synchronize with chan=
ges
            to create_function_arglist.
            * doc/gfortran/naming-and-argument-passing-conventions.rst: Cla=
rify
            the gfortran argument passing conventions with regard to OPTION=
AL
            dummy arguments of intrinsic type.
