cfglayout.c (fixup_reorder_chain): Postpone deleting dead jump tables...
* cfglayout.c (fixup_reorder_chain): Postpone deleting dead
jump tables, move the call to delete_dead_jumptables from here...
(cfg_layout_finalize): ...to here. But rebuild jump labels first.
* cfgrtl.c (cfg_layout_can_merge_blocks_p): When not optimizing,
don't allow merging of blocks that try_redirect_by_replacing_jump
also does not handle when not optimizing.
