Since Tarantool fibers don't respect Lua coroutine switch mechanism, JIT machinery stays unnotified when one lua_State substitutes another one. As a result if trace recording hasn't been aborted prior to fiber switch, the recording proceeds using the new lua_State and leads to a failure either on any further compiler phase or while the compiled trace is executed. This changeset extends <cord_on_yield> routine aborting trace recording when the fiber switches to another one. If the switch-over occurs while mcode is being run the platform finishes its execution with EXIT_FAILURE code and calls panic routine prior to the exit.
