	* regoc.c (dbr_schedule): Added parm to call to df_lr_add_problem.
	* ifcvt.c (if_convert): Ditto.
	* modulo-sched.c (sms_schedule): Ditto.
	* reg-stack.c (reg_to_stack): Ditto.
	* global.c (global_alloc, rest_of_handle_global_alloc): Ditto.
	(rest_of_handle_global_alloc): Removed call to df_set_state.
	* basic_block.h (clear_reg_deaths): New function.
	* flow.c: (clear_reg_deaths): New function.
	(rest_of_handle_life): Added parm to call to df_lr_add_problem and
	df_ur_add_problem.
	* df-scan.c (df_scan_free_internal): Added code to clear new
	bit vectors.
	(df_scan_alloc): Added extra parameter and code to initialize
	new bit vectors.
	(df_scan_dump): Added code to dump new bit vectors.
	(df_problem problem_SCAN): Added extra field.
	(df_scan_add_problem): Added flags parameter.
	(df_rescan_blocks): Added code to remove deleted blocks from
	bitmap and extra parm to call to df_scan_alloc.
	(df_insn_create_insn_record): Removed return value.
	(df_set_state): Removed function.
	(df_ref_record, df_bb_refs_record, df_record_entry_block_defs,
	df_record_exit_block_uses): Changed the way flags are processed.
	(df_bb_refs_record, df_refs_record, df_record_exit_block_uses): 
	Restructured scanning to fixed hard regs so bitmaps could be
	recorded for later use.
	(df_has_eh_preds): Now public.
	* df-core.c (df_mvs_dump, df_set_flags, df_clear_flags,
	df_delete_basic_block): New function.
	(df_init): Changed location of flags.
	(df_add_problem): Added flags parameter and the way flags are
	processed.
	(df_insn_uid_debug, df_ref_debug, debug_df_defno, debug_df_ref,
	debug_df_chain): Improved debugging output.
	(clear_df): Added call to clear_reg_deaths.
	* df.h: Some reordering to remove forward references.
	(dataflow.flags): New field.
	(df.flag): Deleted field.
	(df_alloc_function): Added additional bitmap parameter.
	(df_dependent_problem_function): New type.
	(df_problem.changeable_flags): New field.
	(df_ref_flags.DF_SCAN_INITIAL,
	DF_SCAN_GLOBAL, DF_SCAN_POST_ALLOC, df_state): Removed.
	(df_refs_chain_dump, df_ref_debug, df_chain_dump): Removed df
