* tracer.c (rest_of_handle_tracer): We already cleaned
up the CFG in tracer() so don't do it here again.
* cfgcleanup.c (rest_of_handle_jump2): Don't repeat
cleanup_cfg here, either. And don't call renumber_insns.
* cfgrtl.c (rtl_verify_flow_info_1): Don't verify that BB_END
and BB_HEAD are in the insn stream here. Instead make sure
that BB_INSN is valid on all insns. Also, do check here that
there are no pending branch predictions...
(rtl_verify_flow_info): ...instead of doing it here. Checks
for BB_END and BB_HEAD moved from rtl_verify_flow_info_1 to
here.
