	* predict.c (maybe_hot_frequency_p): New parameter fun.  Use its decl
	instead of current_function_decl, use profile_status_for_function and
	ENTRY_BLOCK_PTR_FOR_FUNCTION with fun instead of their cfun variants.
	(maybe_hot_count_p): New parameter fun, use
	profile_status_for_function instead of its cfun_variant.
	(maybe_hot_bb_p): New parameter fun, checking-assert it, pass it to
	all callees.
	(maybe_hot_edge_p): Pass cfun to maybe_hot_count_p and
	maybe_hot_frequency_p.
	(probably_never_executed_bb_p): New parameter fun, use its decl
	instead of current_function_decl.
	(optimize_bb_for_size_p): Pass cfun to maybe_hot_bb_p.
	(rtl_profile_for_bb): Likewise.
	(compute_function_frequency): Pass cfun to maybe_hot_bb_p and
	probably_never_executed_bb_p.
	* tree-ssa-operands.c (ssa_operands_active): New operator fun.  Use it
	instead of cfun.
	(update_stmt_operands): Pass cfun as an argument of
	ssa_operands_active.
	(swap_tree_operands): Likewise.
	* gimple-iterator.c (update_modified_stmt): Likewise.
	(update_modified_stmts): Likewise.
	* tree-flow-inline.h (delink_stmt_imm_use): Likewise.
	* tree-ssa.c (delete_tree_ssa): Likewise.
	* bb-reorder.c (bb_to_key): Pass cfun to probably_never_executed_bb_p.
	(push_to_next_round_p): Likewise.
	(find_rarely_executed_basic_blocks_and_crossing_edges ): Likewise.
	* cfg.c: Inlude tree.h.
	(check_bb_profile): Use profile_status_for_function,
	EXIT_BLOCK_PTR_FOR_FUNCTION and ENTRY_BLOCK_PTR_FOR_FUNCTION with
	DECL_STRUCT_FUNCTION (current_function_decl) instead of their cfun
	variants.
	(dump_bb_info): Pass DECL_STRUCT_FUNCTION (current_function_decl) to
	maybe_hot_bb_p and probably_never_executed_bb_p.
	* gimple-pretty-print.c (gimple_dump_bb_buff): Checking-assert that
	DECL_STRUCT_FUNCTION (current_function_decl) is not NULL.  Pass it to
	dump_histograms_for_stmt.
	(dump_gimple_mem_ops): Pass DECL_STRUCT_FUNCTION (current_function_decl)
	as an argument to dump_gimple_mem_ops.
	* tree-cfg.c (dump_function_to_file): Rename parameter fn to fndecl.
	Do not change cfun.  Change and restore current_function_decl.
	* Makefile.in (cfg.o): Include TREE_H in dependencies.
