The multiorder radix tree code is being removed, so remove the
benchmarking of its performance.

2956c6644b radix tree: Remove split/join code 
radix_tree_split and radix_tree_join were never used upstream.  Remove
them; if they're needed in future they will be replaced by XArray
equivalents.

cfa40bcfd6 radix tree test suite: benchmark for iterator 
This adds simple benchmark for iterator similar to one I've used for
commit 78c1d78488 ("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.
