re PR tree-optimization/53226 (Endless loop in forwprop)
PR tree-optimization/53226
* tree-ssa-forwprop.c (ssa_forward_propagate_and_combine): Remove
prev and prev_initialized vars, gimple_set_plf (stmt, GF_PLF_1, false)
before processing it and gimple_set_plf (stmt, GF_PLF_1, true) if it
doesn't need to be revisited, look for earliest stmt with
!gimple_plf (stmt, GF_PLF_1) if something changed.
* gcc.c-torture/compile/pr53226.c: New test.
