Hi, Sergey!

Thanks for the patch!

This patch moves the aforementioned test from the <misc> to the <trace/>
directory, includes it in <index>, and names the subtest.

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.
