Don't split non-critical edges in crited
gcc/ChangeLog:
* tree-cfg.h (split_critical_edges): Add for_edge_insertion_p
parameter with default value false to declaration.
(split_edges_for_insertion): New inline function. Wrapper for
split_critical_edges with for_edge_insertion_p = true.
* tree-cfg.c (split_critical_edges): Don't split non-critical
edges if for_edge_insertion_p is false. Fix whitespace.
* tree-ssa-pre.c (pass_pre::execute): Call
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.
(pass_data_sink_code): Update function name in the comment.
