re PR rtl-optimization/2001 (Inordinately long compile times in reload CSE regs)
PR opt/2001
* bb-reorder.c (maybe_duplicate_computed_goto_succ): New.
(make_reorder_chain_1): Call it.
* function.h (struct function): Add computed_goto_common_label,
computed_goto_common_reg.
* function.c (free_after_compilation): Zap them.
* stmt.c (expand_computed_goto): Use them to produce one
indirect branch per function.
