gcse.c (delete_null_pointer_checks_1): Inform caller if any null pointer checks were eliminated.
* 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..
