Remove field 'address'. (temp_slot_address_table): New hash table of address -> temp slot. (struct temp_slot_address_entry): New struct, items for the table.

(find_temp_slot_from_address): Rewrite to use the new hash table. (remove_unused_temp_slot_addresses): Remove addresses of temp slots that have been made available. (remove_unused_temp_slot_addresses_1): Call-back for htab_traverse, worker function for remove_unused_temp_slot_addresses. (assign_stack_temp_for_type): Don't clear the temp slot address list. Add the temp slot address to the address -> temp slot map. (update_temp_slot_address): Update via insert_temp_slot_address. (free_temp_slots): Call remove_unused_temp_slot_addresses. (pop_temp_slots): Likewise. (init_temp_slots): Allocate the address -> temp slot map, or empty the map if it is already allocated. (prepare_function_start): Initialize temp slot processing.
