+ This function is called to execute an EBC CALLEX instruction.\r
+ The function check the callee's content to see whether it is common native\r
+ code or a thunk to another piece of EBC code.\r
+ If the callee is common native code, use EbcLLCAllEXASM to manipulate,\r
+ otherwise, set the VM->IP to target EBC code directly to avoid another VM\r
+ be startup which cost time and stack space.\r
