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. The regression hunt used the minimized test case from comment #2 on i686-pc-linux-gnu, compiled with -O2 -fnon-call-exceptions.
