PR tree-optimization/70623
* tree-ssa-pre.c (changed_blocks): Make global ...
(compute_antic): ... local here. Move and fix worklist
handling here. Do not clear EDGE_DFS_BACK or call mark_dfs_back_edges.
(compute_antic_aux): Add dumping for MAX assumed succs. Remove
worklist handling, dump when ANTIC_IN changed.
(compute_partial_antic_aux): Remove worklist handling.
(init_pre): Do not compute post dominators. Add a comment about
the CFG order chosen.
(fini_pre): Do not free post dominators.
* gcc.dg/torture/pr70623.c: New testcase.
* gcc.dg/torture/pr70623-2.c: Likewise.
