Allow single-lane SLP in-order reductions
The single-lane case isn't different from non-SLP, no re-association
implied. But the transform stage cannot handle a conditional reduction
op which isn't checked during analysis - this makes it work, exercised
with a single-lane non-reduction-chain by gcc.target/i386/pr112464.c
* tree-vect-loop.cc (vectorizable_reduction): Allow
single-lane SLP in-order reductions.
(vectorize_fold_left_reduction): Handle SLP reduction with
conditional reduction op.
