Subject: bitmap.h (bitmap_and_into): Update prototype.

	* bitmap.h (bitmap_and_into): Update prototype.
	* bitmap.c (bitmap_and_into): Return true if the target bitmap
	changed, false otherwise.

	* df.h (df_dump_insn_problem_function): New function type.
	(struct df_problem): Add two functions, to dump just before and
	just after an insn.
	(DF_RD_PRUNE_DEAD_DEFS): New changable flag.
	(df_dump_insn_top, df_dump_insn_bottom): New prototypes.
	* df-core (df_dump_region): Use dump_bb.
	(df_dump_bb_problem_data): New function.
	(df_dump_top, df_dump_bottom): Rewrite using df_dump_bb_problem_data.
	(df_dump_insn_problem_data): New function.
	(df_dump_insn_top, df_dump_insn_bottom): New functions.
	* df-scan.c (problem_SCAN): Add NULL fields for new members.
	* df-problems.c (df_rd_local_compute): Ignore hard registers if
	DF_NO_HARD_REGS is in effect.
	(df_rd_transfer_function): If DF_RD_PRUNE_DEAD_DEFS is in effect,
	prune reaching defs using the LR problem.
	(df_rd_start_dump): Fix dumping of DEFs map.
	(df_rd_dump_defs_set): New function.
	(df_rd_top_dump, df_rd_bottom_dump): Use it.
	(problem_RD): Add NULL fields for new members.
	(problem_LR, problem_LIVE): Likewise.
	(df_chain_bb_dump): New function.
	(df_chain_top_dump): Dump only for artificial DEFs and USEs,
	using df_chain_bb_dump.
	(df_chain_bottom_dump): Likewise.
	(df_chain_insn_top_dump, df_chain_insn_bottom_dump): New functions.
	(problem_CHAIN): Add them as new members.
	(problem_WORD_LR, problem_NOTE): Add NULL fields for new members.
	(problem_MD): Likewise.
	* cfgrtl.c (rtl_dump_bb): Use df_dump_insn_top and df_dump_insn_bottom.
	(print_rtl_with_bb): Likewise.

	* dce.c (init_dce): Use DF_RD_PRUNE_DEAD_DEFS.
	* loop-invariant.c (find_defs): Likewise.
	* loop-iv.c (iv_analysis_loop_init): Likewise.
	* ree.c (find_and_remove_re): Likewise.
	* web.c (web_main): Likewise.
