[Tarantool-patches] [PATCH luajit] LJ_GC64: Fix lua_concat().

[Maxim Kokryashkin]

Hi, Sergey!
Thanks for the fixes!
LGTM, except for the single comment below.

I am really sorry, that I didn't noticed that in the first round,
but the test case can be reduced a bit more. We don't really need
the `Info` structure and can use some basic type like `int`, for
example. One might argue that such change can reduce the readability
a bit, so I leave the final decision up to you.

This patch LGTM too. However, please re-send the whole
series as `v2` if you'll need to do similar changes next time.
