  | commit basepoints/gcc-14-4089-gd45ddc2c04e
  | Author: Richard Biener <rguenther@suse.de>
  | Date:   Thu Sep 14 13:06:51 2023 +0200
  | 
  |     tree-optimization/111294 - backwards threader PHI costing
  |     
  |     This revives an earlier patch since the problematic code applying
  |     extra costs to PHIs in copied blocks we couldn't make any sense of
  |     prevents a required threading in this case.  Instead of coming up
  |     with an artificial other costing the following simply removes the
  |     bits.
