* tree-optimize.c (pass_cleanup_cfg_post_optimizing): Enable listing.
* tree-flow.h (bsi_commit_one_edge_insert): Extern decl.
* tree-outof-ssa.c (rewrite_trees): Don't commit edges here.
(same_stmt_list_p): New. Return TRUE if edge is to be forwarded.
(identical_copies_p): New. Return true is two copies are the same.
(identical_stmt_lists_p): New. Return true if stmt lists are the same.
(analyze_edges_for_bb): New. Determine how best to insert edge stmts
for a basic block.
