8e395210f50f Refactor gen_x86 to use an interface more like gen_arm and to remove the need for the caller to decide whether an 8-bit or 32-bit displacement is needed in the rdisp functions. Update m68k_to_x86 to use the new version of the gen_x86 functions and do some minor refactoring there in the process
