	gcc            : ChangeLog gcse.c rtl.h toplev.c 

Log message:
	* gcse.c (delete_null_pointer_checks_1): Inform caller if any
	null pointer checks were eliminated.  Update prototype.
	(delete_null_pointer_checks): Similarly.
	* rtl.h (delete_null_pointer_checks): Update prototype.
	* toplev.c (rest_of_compilation): Only run cleanup_cfg if
	delete_null_pointer_checks deletes one or more null
	pointer checks.  Do not run cleanup_cfg before gcse, the
	CFG is accurate and optimized at that point..
