The flags are arranged such that we can manipulate them either
a whole, or as individual bytes.  The computation within
cpu_get_tb_cpu_state is now reduced to a single load and mask.

Current migration code cannot handle some data structures such as
QTAILQ in qemu/queue.h. Here we extend the signatures of put/get
in VMStateInfo so that customized handling is supported. put now
will return int type.

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.

Emulating LL/SC with cmpxchg is not correct, since it can
suffer from the ABA problem.  However, portable parallel
code is written assuming only cmpxchg which means that in
practice this is a viable alternative.

This avoids having to manually swap them around when swapping to and
from PALmode.  We simply encode the shadow registers into the translation.

The VMStateDescription version changes, because the meaning of "shadow"
changes in the save file when in PALmode.  It would be possible to fix
this, but I don't think it's worth the effort.

After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

Commit b758aca1 (target-alpha: Enable
the alpha-softmmu target.) introduced cpu_{save,load}() functions but
didn't define CPU_SAVE_VERSION, so they were never registered.

Drop cpu_{save,load}() and register the VMStateDescription via DeviceClass.
This operates on the AlphaCPU object instead of CPUAlphaState.

With all of the pre-existing code that would not compile gone,
this is the earliest point at which the target can be enabled.

There is no machine defined yet, so this will crash on startup.
Enable the target anyway, to make sure that further compilation
problems do not creep back in.
