To better visualize the data dumped at the end of a TB,
left-align it (padding it with 0).

This doesn't quite work, because

However, I also noticed that we shouldn't be printing ".quad" for 32-bit hosts
either. So I'll just split this into two separate qemu_log invocations, based
on sizeof(tcg_target_ulong).
