	* tree-flow.h (struct pre_expr_d): Remove forward declaration.
	(add_to_value): Remove.
	(print_value_expressions): Likewise.
	* tree-ssa-pre.c (add_to_value): Make static.
	(print_value_expressions): Likewise.
	* gimple.h (gimple_adjust_this_by_delta): Remove.
	* gimple-fold.c (gimple_adjust_this_by_delta): Likewise.
