    Fortran: fix passing of optional dummy as actual to optional argument
[PR55978]

    gcc/fortran/ChangeLog:

            PR fortran/55978
            * trans-array.cc (gfc_conv_array_parameter): Do not dereference
            data component of a missing allocatable dummy array argument for
            passing as actual to optional dummy.  Harden logic of presence
            check for optional pointer dummy by using TRUTH_ANDIF_EXPR instead
            of TRUTH_AND_EXPR.
