    PR tree-optimization/54713

    * 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.
