add costing to SLP vectorized PHIs
I forgot to cost vectorized PHIs. Scalar PHIs are just costed
as scalar_stmt so the following costs vector PHIs as vector_stmt.
2020-11-04 Richard Biener <rguenther@suse.de>
* tree-vectorizer.h (vectorizable_phi): Adjust prototype.
* tree-vect-stmts.c (vect_transform_stmt): Adjust.
(vect_analyze_stmt): Pass cost_vec to vectorizable_phi.
* tree-vect-loop.c (vectorizable_phi): Do costing.
