Speeds up PIIX4 which resolves an old TODO. Also makes PIIX4 compatible with Xen

Next patches in this series will delay the polling
and checking of buffers until either the SVQ is
full or control commands shadow buffers are full,
no longer perform an immediate poll and check of
the device's used buffers for each CVQ state load command.
To achieve this,
We duplicate "cmd" as strtok may modify its argument, but we forgot
to free it later. Furthermore, add_semihosting_arg doesn't take
responsibility for this memory either (it strdup's the argument).

We have several copies of this function (or equivalent).
Expose the one already present in tcg-op-ldst.c.
Then, some target cleanups while searching for "ext8[us]".
