Message:

VMM/IEM: In order to get rid of most impossible threaded functions, an IEM_MC_F_XXX parameter is added to IEM_MC_BEGIN that allows specifying if a block is only for 64-bit mode or 386+ or not for 286 or older. It can be extended with more info later, as needed. [missing header change] bugref:10369
