Add some tests for checking that we can migrate debug state correctly: setup
some breakpoints/watchpoints/single-stepping, migrate, and then check that we
get the expected exceptions.

The 3 patches in this series add tests for breakpoints, watchpoints, and
single-stepping one patch at a time.  Each patch adds a migration test and a
sanity test (to test that debugging works with no migration).

Note that this is limited to 64-bits and a single vcpu. Also note that some of
the code, like reset_debug_state, is borrowed from kvm selftests.

Ricardo Koller (3):
  arm64: debug: add a migration test for breakpoint state
  arm64: debug: add a migration test for watchpoint state
  arm64: debug: add a migration test for single-step state
