The helper functions all access ppc-specific fields only so don't bother
to change arguments to PowerPCCPU and use env_ptr instead.
No functional change.

Potentially env could be NULL whereas cpu would still be valid and
correspond to a previous env.
Wrapping this in qemu_get_cpu(), env is no longer needed, so simplify
code that existed before 55e5c28502.

Since we still need env for ppc-specific fields, obtain it via the new
env_ptr fields to avoid "cpu" name conflicts between CPUState and
PowerPCCPU for now.
This fixes a potential issue with env being NULL at the end of the loop
but cpu still being a valid pointer corresponding to a previous env.

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions.
The field may not be called "env" due to it being poisoned.

Explictly NULL it on CPU reset since it was located before breakpoints.
Change vapic_report_tpr_access() argument to CPUState. This also

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.

Combine this with breakpoint handler registration, guarding both with
tcg_enabled() to suppress also TCG init for qtest. Rename the handler to

Split out TCG initialization from cpu_cris_init(). Avoid CPUCRISState
dependency for v10-specific initialization and for non-v10 by inlining
the decision into the initfn as well.

The QOM realizefn cannot depend on errp being non-NULL as in
