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

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.

Make the output of radix tree test suite less verbose by default and add
-v and -vv command line options for increasing level of verbosity.

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.
