PR tree-optimization/80457
* tree-vect-stmts.c (vect_model_simple_cost): Model the cost
of all arguments to a statement as scalar_to_vec operations.
(vectorizable_call): Adjust call to vect_model_simple_cost for
new parameter.
(vectorizable_conversion): Likewise.
(vectorizable_assignment): Likewise.
(vectorizable_shift): Likewise.
(vectorizable_operation): Likewise.
(vectorizable_comparison): Likewise.
(vect_is_simple_cond): Record the def types for operands.
(vectorizable_condition): Likewise, call vect_model_simple_cost.
* tree-vectorizer.h (vect_model_simple_cost): Add new parameter
for statement argument count.
