    middle-end/96466 - fix VEC_COND isel/expansion issue

    We need to avoid forcing BLKmode for truth vectors, instead do as
    other code and use VOIDmode so layout_type can pick a suitable and
    consistent mode.  RTL expansion of vect_cond_mask also needs to deal
    with CONST_INT operands which means passing the mode explicitely.

            * internal-fn.c (expand_vect_cond_mask_optab_fn): Use
            appropriate mode for force_reg.
            * tree.c (build_truth_vector_type_for): Pass VOIDmode to
            make_vector_type.

            * gcc.dg/pr96466.c: New testcase.
