Check for thread select instructions rather than output.

Fun fact: it seems that register read outputs immediately while thread select can output after register read output. Weird.

Add FreeBSD/aarch64 test.

@labath, could you give me at least a rough idea how you feel about this one? I'd like to know if I need to change the test code before I start adding coredumps for more architectures.
