testsuite: Fix loop-interchange-16.c
Prevent loop unrolling of the innermost loop because otherwise we are
left with no loop interchange for targets like s390 which have a more
aggressive loop unrolling strategy.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/loop-interchange-16.c: Prevent loop unrolling
of the innermost loop.
