This enables the multi-threaded system emulation by default for ARMv7 and ARMv8 guests using the x86_64 TCG backend. This is because on the guest side:
- The ARM translate.c/translate-64.c have been converted to - use MTTCG safe atomic primitives - emit the appropriate barrier ops - The ARM machine has been updated to - hold the BQL when modifying shared cross-vCPU state - defer powerctl changes to async safe work
All the host backends support the barrier and atomic primitives but need to provide same-or-better support for normal load/store operations.
