PR81815: Invalid conditional reduction

We weren't checking whether the phi in a conditional reduction was
used by the condition itself (which isn't a case we handle).

        * tree-vect-loop.c (vect_is_simple_reduction): Simply checks for
        the phi SSA_NAME.  Check that the condition in a COND_EXPR does
        not depend on the phi.
