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.

int tcg_cpus_exec(CPUState *cpu);
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. As a byproduct, this allows us to completely remove parallel_cpus. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
