For uniprocessors, SH4 uses optimistic restartable atomic sequences. Upon an interrupt, a real kernel would simply notice magic values in the registers and reset the PC to the start of the sequence. For QEMU, we cannot do this in quite the same way. Instead, we notice the normal start of such a sequence (mov #-x,r15), and start a new TB that can be executed under cpu_exec_step_atomic.
