Good for the I386 halted attribute, as it was a mistake to put in in the
hflags. For the memory, hflags should contain only parts of the CPU
state known at translation time and should be equal to tb->flags. Most
CPUs (including x86 !) do not follow this sane rule.
For cpu_info_ip, it would be simpler to return an uint64_t containing
the PC. I don't think the sparc case with npc really matters.
