* gcse.c (gcse_main): Don't rebuild the CFG here.
        (delete_null_pointer_checks): Likewise.
        * ssa.c (convert_to_ssa): Likewise.
        * toplev.c (rest_of_compilation): Do it here instead.  Combine
        sequential calls to TIMEVAR.  Consistently use `insns' instead of
        `get_insns()'.  Always split insns after reload when optimizing.
