We have confused the number of instructions that have been
executed in the TB with the number of instructions needed
to repeat the I/O instruction.
We have used cpu_restore_state_from_tb, which means that
the guest pc is pointing to the I/O instruction. The only
time the answer to the later question is not 1 is when
MIPS or SH4 need to re-execute the branch for the delay
slot as well.
We must rely on cpu->cflags_next_tb to generate the next TB,
as otherwise we have a race condition with other guest cpus
within the TB cache.
