[Tarantool-patches] [PATCH luajit 0/2] Fix lua_yield from the C hook.

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

This patchset fixes the behaviour of the `lua_yield()` invocation inside
C hooks. The first patch fixes the behaviour for non-GC64 mode, but the
GC64 mode is still failing with a core dump. The second patch fixes
behaviour for the GC64 mode as well.

This patchset is based on the our C tests to be introduced, but their
patch set has 2 LGTMs, so I just checkout this branch from the branch
with C tests.
