* init.c: Do not adjust IP of an imported VMS exception of ia64.
LIB$STOP is called to raise an exception and the IP of the exception
is the instruction right after the call.
(__gnat_adjust_context_for_raise, AIX): Implement.
(__gnat_error_handler, AIX): Accept SIGINFO related arguments and call
adjust_context_for_raise before Raise_From_Signal_Hanler.
(__gnat_install_handler, AIX): Add SA_SIGINFO to the sa_flags, to ensure
siginfo is passed to the handler, necessary to let the zcx propagation
engine unwind past it.
