	* df-scan.c (df_scan_free_bb_info): Added basic block parameter to
	be able to clean out basic block when not necessary.
	(df_scan_free): Fixed to properly delete information if df is
	unused before calling df_finish.
	(df_scan_alloc, df_rescan_blocks, df_reg_chain_unlink,
	df_insn_create_insn_record, df_bb_refs_record): Fixed formatting
	or comment typos.
	(df_bb_refs_delete): New function.
	(df_refs_delete): Moved per block code to df_bb_refs_delete.
	* df-core.c (df_set_blocks): Added code to properly clean out
	unused blocks if they are not part of the blocks to consider.
	Added additional null check.
	(df_compact_blocks): Added basic block parameter to free_bb_fun to
	be able to clean out basic block when not necessary
	* df.h (df_free_bb_function): Ditto.
	(df_bb_refs_delete): New function.
	* df-problems.c (df_ru_free_bb_info, df_rd_set_bb_info,
	df_lr_set_bb_info, df_ur_free_bb_info, df_urec_free_bb_info):Added
	basic block parameter to be able to clean out basic block when not
	necessary.
	(df_ru_alloc, df_rd_alloc): Fixed dyslexic overflow test.
	(df_ru_free, df_rd_free, df_lr_free, df_ur_free, df_urec_free):
	Fixed to properly delete information if df is unused before
	calling df_finish.
