PR tree-optimization/89463
* tree-ssa-dce.c (remove_dead_stmt): Take output vector to
queue edges to remove.
(eliminate_unnecessary_stmts): Remove dead PHIs alongside
dead stmts. Delay edge removal until PHIs are removed to
make debug-stmt creation not confused by seemingly degenerate
PHIs.
* gcc.dg/guality/pr89463.c: New testcase.
