Under some circumstance (library loaded with the main program), TLS initial-exec model can be applied to local-dynamic access(es). We could use some simple heuristic to decide the update at function level: * If there is equal or less than a number of TLS local-dynamic access(es) in the function, use TLS initial-exec model. (the threshold which default to 1 is controlled by hidden option)
