This implements this. 2021-11-18 Richard Biener PR tree-optimization/103277 * tree-ssa-dse.c (need_ab_cleanup): New. (dse_optimize_redundant_stores): Adjust. (delete_dead_or_redundant_assignment): Get extra need_ab_cleanup argument and set when abnormal cleanup is needed. (dse_optimize_call): Adjust. (dse_optimize_stmt): Likewise. (pass_dse::execute): Allocate and deallocate need_ab_cleanup. Perform abnormal cleanup. * tree-ssa-dse.h (delete_dead_or_redundant_assignment): Adjust. * gcc.dg/pr103277.c: New testcase.

Yep, I know - it is modref based DSE that lets us to enable that call as dead. So the bug is technically mine if Richi decides to pass it to me :) We need to keep track if cleanup_cfg is needed by testing whether removed call had multpile exit edges, right?
