re PR target/17052 (altivec varargs failure if no optimization)
PR target/17052
* config/rs6000/rs6000.h (machine_function): Remove sysv_varargs_p.
* config/rs6000/sysv4.h (RS6000_VARARGS_AREA): Use
current_function_stdarg in place of sysv_varargs_p.
* config/rs6000/rs6000.c (setup_incoming_varargs): Don't set
sysv_varargs_p.
