re PR middle-end/32018 (ICE on optimization)
PR middle-end/32018
* tree-ssa-threadupdate.c (thread_through_loop_header): Use
set_loop_copy.
(thread_through_all_blocks): Call initialize_original_copy_tables
and free_original_copy_tables.
* cfgloopmanip.c (duplicate_loop, duplicate_loop_to_header_edge):
Use set_loop_copy.
* tree-cfg.c (tree_duplicate_sese_region): Ditto.
* cfghooks.c (duplicate_block): Use get_loop_copy.
* cfg.c: Include cfgloop.h.
(loop_copy): New hash table.
(initialize_original_copy_tables): Initialize loop_copy table.
(free_original_copy_tables): Free loop_copy table.
(copy_original_table_clear, copy_original_table_set,
set_loop_copy, get_loop_copy): New functions.
(set_bb_original, set_bb_copy): Use copy_original_table_set.
* cfgloop.h (struct loop): Remove copy field.
* Makefile.in (cfg.o): Add CFGLOOP_H dependency.
* basic-block.h (set_loop_copy, get_loop_copy): Declare.
