[Tarantool-patches] [PATCH v1 luajit 07/41] perf: adjust coroutine-ring in LuaJIT-benches

[Sergey Kaplun]

This patch adjusts the aforementioned test to use the benchmark
framework introduced before. The default arguments are adjusted
according to the <PARAM_x86.txt> file. The arguments to the script still
can be provided in the command line run.
