[Tarantool-patches] [PATCH luajit v1] Fix BC_UCLO insertion for returns.

[Igor Munkin]

Sergey,

Thanks for the patch! FYI, I changed Co-authored-by tag to Helped-by,
since the only author of the patch is Mike Pall.

I've checked the patchset into all long-term branches in
tarantool/luajit and bumped a new version in master, release/2.11 and
release/2.10.
