Support single def-use cycle optimization for SLP reduction vectorization
We can at least mimic single def-use cycle optimization when doing
single-lane SLP reductions and that's required to avoid regressing
compared to non-SLP.
* tree-vect-loop.cc (vectorizable_reduction): Allow
single-def-use cycles with SLP.
(vect_transform_reduction): Handle SLP single def-use cycles.
(vect_transform_cycle_phi): Likewise.
* gcc.dg/vect/slp-reduc-12.c: New testcase.
