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.
