    Generic vector op costing adjustment

    This is a small adjustment to the work done for PR108752 and
    better reflects the cost of the generated sequence.

            PR tree-optimization/108752
            * tree-vect-stmts.cc (vectorizable_operation): For bit
            operations with generic word_mode vectors do not cost
            an extra stmt.  For plus, minus and negate also cost the
            constant materialization.=
