16a1b6e97c target-cris: update CPU state save/load to use VMStateDescription
Update the CRIS CPU state save/load to use a VMStateDescription struct
rather than cpu_save/cpu_load functions.

Have to define TLBSet struct.
Multidimensional arrays in C are a mess, just unroll them.

[PMM:
 * expand commit message a little since it's no longer one patch in
   a 35-patch series
 * add header/copyright comment to machine.c; credited copyright is
   Red Hat and author is Juan, since this commit gives the file all-new
   contents; license is LGPL-2-or-later, to match other target-cris code
 * remove hardcoded tab
 * add fields for locked_irq, interrupt_vector, fault_vector, trap_vector
 * drop minimum_version_id_old fields
 * bump version_id to 2 as we are not compatible with old state format
 * remove unnecessary hw/boards.h include
 * update to register via dc->vmsd]

00b941e581 cpu: Turn cpu_get_phys_page_debug() into a CPUClass hook
Change breakpoint_invalidate() argument to CPUState alongside.

Since all targets now assign a softmmu-only field, we can drop helpers
cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd().

Prepares for changing cpu_memory_rw_debug() argument to CPUState.

6e42be7cd1 cpu: Drop unnecessary dynamic casts in *_env_get_cpu()
A transition from CPUFooState to FooCPU can be considered safe,
just like FooCPU::env access in the opposite direction.
The only benefit of the FOO_CPU() casts would be protection against
bogus CPUFooState pointers, but then surrounding code would likely
break, too.

This should slightly improve interrupt etc. performance when going from
CPUFooState to FooCPU.
For any additional CPU() casts see 3556c233d9
(qom: allow turning cast debugging off).

b21bfeead2 target-cris: Override do_interrupt for pre-v32 CPU cores
Instead of forwarding from cris_cpu_do_interrupt() to do_interruptv10(),
override CPUClass::do_interrupt with crisv10_cpu_do_interrupt() in the
newly introduced class_init functions.

97a8ea5a3a cpu: Replace do_interrupt() by CPUClass::do_interrupt method
This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU
families.

fadf982584 cpu: Introduce ENV_OFFSET macros
Introduce ENV_OFFSET macros which can be used in non-target-specific
code that needs to generate TCG instructions which reference CPUState
fields given the cpu_env register that TCG targets set up with a
pointer to the CPUArchState struct.

6ae064fc67 target-cris: Introduce CRISCPU subclasses
Use class_init functions to initialize the VR in preparation for
overriding v32+ behavior there.

Move cpu_cris_init() to cpu.c and hook up a class_by_name callback.

This change leads to unknown -cpu model names no longer falling back
to a CPU with VR 32 but instead returning NULL.
