Silent truncation of size_t to uint32 in mov (<mem>, <size_t>) case about xbyak

Thank you for your advice.
How about f03bbc2 ?

Thank you for submitting a fix.
I'm afraid it's not quite complete, though:
mov (qword[rbx], 0xf2345678);
The above will not throw an error and will become:
mov qword ptr [rbx],0FFFFFFFFF2345678h
(mov (dword[rbx], 0xf2345678); (dword instead of qword) should still be allowed as before).
