Log:
    PR tree-optimization/54713
    * fold-const.c (vec_cst_ctor_to_array): Give up if vector CONSTRUCTOR
    has vector elements.
    (fold_ternary_loc) <case BIT_FIELD_REF>: Likewise.
    * tree-vect-generic.c (vector_element): Don't rely on CONSTRUCTOR elts
    indexes.  Use BIT_FIELD_REF if CONSTRUCTOR has vector elements.
    (lower_vec_perm): Use NULL_TREE CONSTRUCTOR indexes.

    * gcc.c-torture/compile/pr54713-1.c: New test.
    * gcc.c-torture/compile/pr54713-2.c: New test.
    * gcc.c-torture/compile/pr54713-3.c: New test.
