radix tree test suite: benchmark for iterator
This adds simple benchmark for iterator similar to one I've used for
commit 78c1d78488a3 ("radix-tree: introduce bit-optimized iterator")
Building with make BENCHMARK=1 set radix tree order to 6, this allows to
get performance comparable to in kernel performance.
