    d: Fix ICE in expand_intrinsic_vaarg

    Both intrinsics did not handle the case where the va_list object comes
    from a ref parameter.

    gcc/d/ChangeLog:

            PR d/96140
            * intrinsics.cc (expand_intrinsic_vaarg): Handle ref parameters as
            arguments to va_arg().
            (expand_intrinsic_vastart): Handle ref parameters as arguments to
            va_start().

    gcc/testsuite/ChangeLog:

            PR d/96140
            * gdc.dg/pr96140.d: New test.
