Writing TCG micro-ops to do complicated tasks done by helper functions might
not so easy, that why there are helper functions, we only need to do a simple
call. Perhaps you need to write TCG micro-ops to achieve what helper functions
do on your own, then you can replace all helper function calls with those TCG
micro-ops.
