insns.dat: add "MOV reg64,imm32" as a special rule

Browse Source 
Add "MOV reg64,imm32" as a special rule, to handle the case of
"mov rax,dword <foo>", where <foo> is sign-extended; this is a 7-byte
form, as opposed to "mov eax,<foo>" (5 bytes) and "mov rax,<foo>" (10
bytes).

At some point, the optimizer needs to be able to handle these.
