[Tarantool-patches] [PATCH luajit v2 0/5] jit: add exception unwinding

[Maxim Kokryashkin]

This patchset adopts the LuaJIT machinery for unwinding
exceptions raised while trace execution.

The snap-restore test is disabled, since after this patchset
it requires dynamic calculation for amount of allocated
stack slots. That test should be rewritten in a
less fragile manner.

Changes in v2:
- Fixed comments as per review by Sergey
- Added the test case for IR_RENAME.
