PR tree-optimization/80928
* tree-vect-loop.c (vect_update_vf_for_slp): Amend dumps.
(vect_analyze_loop_operations): Properly guard analysis for
pure SLP case.
(vect_transform_loop): Likewise.
(vect_analyze_loop_2): Also reset SLP type on PHIs.
(vect_model_induction_cost): Do not cost for pure SLP.
(vectorizable_induction): Pass in SLP node, implement SLP vectorization
of induction in inner loop vectorization.
* tree-vect-slp.c (vect_create_new_slp_node): Handle PHIs.
(vect_get_and_check_slp_defs): Handle vect_induction_def.

recursion.
