* dwarf2read.c (stmt_list_hash): New struct.
(type_unit_group): Embed "per_cu" member, remove pointer. New union member "t", move member "tus" into it, all uses updated. New member "hash", replaces member "line_offset, all uses updated. (quick_file_names): Replace member "offset" with "hash", all uses updated. (hash_stmt_list_entry, eq_stmt_list_entry): New functions. (hash_file_name_entry, eq_file_name_entry): Call them. (hash_type_unit_group, eq_type_unit_group): Ditto. (dw2_get_cu, dw2_get_primary_cu): Replace assert with a better one. (dw2_get_file_names_reader): Fix file name table calculation for TUs. (dw2_get_file_names): Update. (create_type_unit_group): Replace "per_cu" arg with "cu". All callers updated. Fix "quick" (.gdb_index) handling. (get_type_unit_group): Replace "per_cu" arg with "cu". All callers updated. (build_type_unit_groups): Don't reset tu_stats.
