Let's return the cc value directly via cpu_env. Unfortunately there
isn't a simple way to calculate the value lazily - one would have to
calculate and store e.g. the population count of the mask and the
result so it can be evaluated in a cc helper.
But as VTM only sets the cc, we can assume the value will be needed soon
either way.

It fixes heap-use-after-free which was found by clang's ASAN.
Control flow of this use-after-free:
main_thread:
* Got SIGTERM and completes main loop
* Calls migration_shutdown
- migrate_fd_cancel (so, migration_thread begins to complete)
- object_unref(OBJECT(current_migration));
migration_thread:
* migration_iteration_finish -> schedule cleanup bh
* object_unref(OBJECT(s)); (Now, current_migration is freed)
* exits
main_thread:
* Calls vm_shutdown -> drain bdrvs -> main loop
-> cleanup_bh -> use after free
If you want to reproduce, these couple of sleeps will help:
vl.c:4613:
migration_shutdown();
+ sleep(2);
migration.c:3269:
+ sleep(1);
trace_migration_thread_after_loop();
migration_iteration_finish(s);
