@ChangeLog:
* "FFI sandwich"(*) detection is introduced. If sandwich is detected
  while trace recording the recording is aborted. The sandwich detected
  while mcode execution leads to the platform panic.
* luaJIT_setmode call is prohibited while mcode execution and leads to
  the platform panic.

(*) The following stack mix is called FFI sandwich.
    | Lua-FFI -> С routine -> Lua-C API -> Lua VM
    This sort of re-entrancy is explicitly not supported by LuaJIT
    compiler. For more info see gh-4427.
