[Tarantool-patches] [PATCH v2 luajit 19/45] test: enable <misc/hook_record.lua> LuaJIT test

[Sergey Kaplun]

This patch moves the aforementioned test from the <misc> to the <trace/>
directory, includes it in <index>, and names the subtest. Also, it
slightly refactors the code to make it closer to our code style.

The test is adjusted to be runable in the test suite by adding the
`jit.flush()` to avoid collisions of traces. Also, the number of
iterations for the compiled loop inside the hook is increased to avoid
hotcount collisions.
