tree-vect-transform.c (vect_get_vec_defs_for_stmt_copy): check if the VEC is not NULL.
* tree-vect-transform.c (vect_get_vec_defs_for_stmt_copy): check if
the VEC is not NULL.
(vectorizable_type_demotion, vectorizable_type_promotion): Check that
get_vectype_for_scalar_type succeeded.
(vectorizable_conversion): Likewise.
