[Tarantool-patches] [PATCH luajit 24/25] test: enable <catch_wrap.lua> LuaJIT test

[Sergey Kaplun]

This patch moves the <catch_wrap.lua> test from the <misc> to <lang>
directory, includes it in <index>, and names subtests. Also, since the
tests may be shuffled, `cp.wrapon()` and `cp.wrapoff()` are used for
each test separately. Also, this patch adds a workaround for the
internal ASAN bug, see details in the comment in the <CMakeLists.txt>.
