ia64.h (struct machine_function): Add n_varargs.

Browse source 
* config/ia64/ia64.h (struct machine_function): Add n_varargs.
        * config/ia64/ia64.c (ia64_compute_frame_size): Use it.
        (ia64_expand_prologue): Likewise.
        (ia64_setup_incoming_varargs): Set it.  Properly skip the current
        argument for stdargs.
