tree-optimization/107672 - avoid vector mode type_for_mode call
The following avoids using type_for_mode on vector modes which might not work for all frontends. Instead we look for the inner mode type and use build_vector_type_for_mode instead. PR tree-optimization/107672 * tree-vect-stmts.cc (supportable_widening_operation): Avoid type_for_mode on vector modes.
