LEA changes behaviour based on the ordering of the prefixes on the
instruction
eg:
66 48 8d 3d ffffffff: lea rdi, [rip - 1]
48 66 8d 3d ffffffff: lea di, [rip - 1]
So we need to know the order of a few of the prefixes.
In the future this should probably be switched to a three deep stack to
have the ordering but for now this'll do
