cpu: Move breakpoints field from CPU_COMMON to CPUState
Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>
