cpus: extract out TCG-specific code to accel/tcg TCG is the first accelerator to register a "CpusAccel" interface on initialization, providing functions for starting a vcpu, kicking a vcpu, sychronizing state and getting virtual clock and ticks.

Clean up header guards that don't match their file name Header guard symbols should match their file name to make guard collisions less likely. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

accel: replace struct CpusAccel with AccelOpsClass This will allow us to centralize the registration of the cpus.c module accelerator operations (in accel/accel-softmmu.c), and trigger it automatically using object hierarchy lookup from the new accel_init_interfaces() initialization step, depending just on which accelerators are available in the code. Rename all tcg-cpus.c, kvm-cpus.c, etc to tcg-accel-ops.c, kvm-accel-ops.c, etc, matching the object type names.

accel/tcg: Precompute curr_cflags into cpu->tcg_cflags The primary motivation is to remove a dozen insns along the fast-path in tb_lookup.
