...so these two tests are simply very slow; if I run them directly, they
take longer than 45s, but eventually finish. So all seems good (in a
slow way) on QEMU + tcg.

On the simulator, running check_gcr_el1_cswitch directly finishes
successfully after several minutes as well; however, I get all the other
failures in tests that I reported in my first mail even when I run them
directly.
