[Tarantool-patches] [PATCH v1 luajit 04/41] perf: adjust array3d 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.

The number of iterations is fixed for this test to avoid OOM errors
for the non-GC64 builds.
