    * expr.c (categorize_ctor_elements_1): Don't assume purpose is
    non-NULL.
    * tree-cfg.c (verify_gimple_assign_single): Add verification of
    vector CONSTRUCTORs.
    * tree-ssa-sccvn.c (vn_reference_lookup_3): For VECTOR_TYPE
    CONSTRUCTORs, don't do anything if element type is VECTOR_TYPE,
    and don't check index.
    * tree-vect-slp.c (vect_get_constant_vectors): VIEW_CONVERT_EXPR
    ctor elements first if their type isn't compatible with vector
    element type.
