c05efcb18e cpu: Add CPUArchState pointer to CPUState
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.

1e45d31b04 target-sh4: Mark as unmigratable
It neither defined CPU_SAVE_VERSION nor implemented cpu{save,load}().
Mark it as unmigratable at device level.

55e5c28502 cpu: Move cpu_index field to CPUState
Note that target-alpha accesses this field from TCG, now using a
negative offset. Therefore the field is placed last in CPUState.

Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.

Move common parts of mips cpu_state_reset() to mips_cpu_reset().

Let CPUClass::reset() call cpu_state_reset() for now.
