[Tarantool-patches] [PATCH luajit 4/4] Fix last commit.

[Sergey Kaplun via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

From: Mike Pall <mike>

(cherry picked from commit 43d0a19158ceabaa51b0462c1ebc97612b420a2e)

The previous commit accidentally removes the check that fusing
optimization isn't performing across the call to the `table.clear()`.
This commit fixes the behaviour by adding the corresponding check that
depends on the first bit of `check` masks in the `noconflict()` routine.

Sergey Kaplun:
* added the description for the problem
