    Fortran  : ICE in resolve_fl_procedure PR95708
    
    Now issues an error "Intrinsic procedure 'num_images' not
    allowed in PROCEDURE" instead of an ICE.

            * intrinsic.c (add_functions): Replace CLASS_INQUIRY with
            CLASS_TRANSFORMATIONAL for intrinsic num_images.
            (make_generic): Replace ACTUAL_NO with ACTUAL_YES for
            intrinsic team_number.
            * resolve.c (resolve_fl_procedure): Check pointer ts.u.derived
            exists before using it.
