    In Array.of and Array.from, fall back to DefineOwnProperty · b23c328f
    dehrenberg authored
    %AddElement is not intended for objects which are not arrays, and
    its behavior may go away with future refactorings. This patch gets
    rid of it if the receiver of from or of is not the intrinsic Array
    object.
    
    Array.of and Array.from previously papered over failures in calling
    [[DefineOwnProperty]] when setting array elements. This patch
    makes them lead to exceptions, and adds tests to assert that
    the appropriate exceptions are thrown.
