        * tree-cfg.h (split_critical_edges): Add for_edge_insertion_p
	parameter with default value false to declaration.

	split_critical_edges with for_edge_insertion_p = true.

	edges if for_edge_insertion_p is false.  Fix whitespace.

	split_edges_for_insertion instead of split_critical_edges.
        * gcc/tree-ssa-tail-merge.c (tail_merge_optimize): Ditto.
        * gcc/tree-ssa-sink.c (pass_sink_code::execute): Ditto.
