jump.c (mark_all_labels): Work in cfglayout mode.
* jump.c (mark_all_labels): Work in cfglayout mode.
* cfgcleanup.c (cleanup_cfg): Do not call delete_dead_jumptables
when in cfglayout mode, because there are no dead jumptables
visible.
* cfgrtl.c (commit_one_edge_insertion): Don't set bb->aux when
in cfglayout mode.
(commit_edge_insertions): Do not allow insertion of instructions
with control flow insns when in cfglayout mode.
