Move the following TCG-specific cpu_loop_exit_*() declarations out of the generic "exec/cpu-common.h" header, to the recently created "accel/tcg/cpu-loop.h" one, documenting them: - cpu_loop_exit_noexc() - cpu_loop_exit_atomic() - cpu_loop_exit_restore() - cpu_loop_exit() Include "accel/tcg/cpu-loop.h" where appropriate.
