[AUTO]: updating luabinding automatically
Update that avoid crash during load resource which serialize by flat buffers
comment line 83

As known,  _glProgramStates is a cocos2d::Map container,it will call object->retain() when insert, and call position->second->release() when erase, so the statement of line 83 is redundant.
If i don't comment line 83, the application will crash when GLProgramStateCache::removeUnusedGLProgramState() is called.
