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.
