All of them [1]. If you have an asymmetric machine, you can disable those flags with the -cpu switch.
Note the default qemu cpu disables many flags, so if one machine has sse4.2 and the other doesn't, migration will still work without disabling anything.
[1] Rather, all flags understood by qemu and kvm that are enabled by the cpu model that you gave to qemu with -cpu.
