* tree-loop-distribution.c (classify_partition): Return
whether a reduction appeared in all partitions and do not
stop builtin detection because of this.
(distribute_loop): Sort a non-builtin partition last if
there's a reduction in all partitions and make sure the
partition prevailing as last is not a builtin.

* gcc.dg/tree-ssa/ldist-26.c: Adjust.
