    vect: Pass truth type to vect_get_vec_defs.

    For conditional operations the mask is loop invariant and cannot be
    stored explicitly.  By default, for reductions, we deduce the vectype
    from the statement or the loop but this does not work for conditional
    operations.  Therefore this patch passes the truth type of the reduction
    input vectype for the mask operand instead.  This will override the
    other choices and make sure we have the proper mask vectype.
