Changes for v10:
- Fixed one case in cpu_throttle_thread, where we were using 
  qemu_global_mutex instead of cpu->lock for the halt_cond.
- Changed qemu_cpu_kick() to ensure we are under the CPU
  lock so we do not miss a notification.
- Added a few more reviewed-bys.

v9: https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg06289.html

Quoting an earlier patch in the series:
"For context, the goal of this series is to substitute the BQL for the
per-CPU locks in many places, notably the execution loop in cpus.c.
This leads to better scalability for MTTCG, since CPUs don't have
to acquire a contended global lock (the BQL) every time they
stop executing code.
See the last commit for some performance numbers."
