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...

target-sh4: Introduce SuperHCPU subclasses

Store legacy name in SuperHCPUClass for -cpu ? and for case-insensitive
class lookup.

List CPUs by iterating over TYPE_SUPERH_CPU subclasses.

target-sh4: Move PVR/PRR/CVR into SuperHCPUClass

They are never changed once initialized, and moving them to the class
will allow to inspect them before instantiating.

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....

target-sh4: Move TCG initialization to SuperHCPU initfn

Add a tcg_enabled() check to suppress it for qtest.

target-sh4: Introduce QOM realizefn for SuperHCPU

Introduce a realizefn and set realized = true in cpu_sh4_init().

target-sh4: Mark as unmigratable

It neither defined CPU_SAVE_VERSION nor implemented cpu{save,load}().
Mark it as unmigratable at device level.

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()....

target-sh4: QOM'ify CPU

Embed CPUSH4State as first member of SuperHCPU.

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