loop-iv: make find_simple_exit static

Function 'find_simple_exit' is used only from loop-iv.c
In 2004-2006 it was also used in predict.c, but since r118694
(992c31e62304ed5d34247dbdef2db276d08fac05) it does not.

gcc/ChangeLog:
	* loop-iv.c (find_simple_exit): Make it static.
	* cfgloop.h: Remove the corresponding prototype.
