update_flow_info error for rs6000-ibm-aix4.1.5 configuration

[David Edelsohn]

	FYI, I am receiving an internal compiler error in
haifa-sched.c:update_flow_info() from the current CVS sources for
rs6000-ibm-aix4.1.5 configuration.

haifa-sched.c:8085: Internal compiler error in function update_flow_info
