PR tree-optimization/58626
* tree-loop-distribution.c (enum rdg_dep_type): Remove
anti_dd, output_dd and input_dd.
(struct rdg_edge): Remove level and relation members.
(RDGE_LEVEL, RDGE_RELATION): Remove.
(dot_rdg_1): Adjust.
(create_rdg_edge_for_ddr): Remove.
(create_rdg_edges_for_scalar): Adjust.
(create_edge_for_control_dependence): Likewise.
(create_rdg_edges): Split into ...
(create_rdg_flow_edges): ... this
(create_rdg_cd_edges): ... and this.
(free_rdg): Adjust.
(build_rdg): Likewise, do not compute data dependences or
add edges for them.
(pg_add_dependence_edges): New function.
(pgcmp): Likewise.
(distribute_loop): First apply all non-dependence based
partition mergings. Then compute dependences between partitions
and merge and order partitions according to them.
* gcc.dg/torture/pr58626.c: New testcase.
