        * c-tree.h (c_mark_addressable): Add array_ref_p argument.
        * c-typeck.c (c_mark_addressable): Likewise.  Look through
        VIEW_CONVERT_EXPR unless array_ref_p and VCE is from VECTOR_TYPE
        to ARRAY_TYPE.
        (build_array_ref): Pass true as array_ref_p to c_mark_addressable.
