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.

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.

6d1bbc6273 target-m68k: Introduce QOM realizefn for M68kCPU
Introduce realizefn and set realized = true in cpu_m68k_init().

Split off GDB registration to a new m68k_cpu_init_gdb() so that it can
be called from the realizefn.

7a9f812b38 target-m68k: Rename CPU subtypes
In the initial conversion of CPU models to QOM types, model names were
mapped 1:1 to type names. As a side effect this gained us a type "any",
which is now a device.

To avoid "-device any" silliness and to pave the way for compiling
multiple targets into one executable, adopt a <name>-<arch>-cpu scheme.

No functional changes for -cpu arguments or -cpu ? output.

087fe4f824 target-m68k: Mark as unmigratable
It neither defined CPU_SAVE_VERSION nor implemented cpu_{save,load}().
Mark M68kCPU as unmigratable at device level.

2dddbc2123 target-m68k: Use type_register() instead of type_register_static()
According to its documentation, type_register_static()'s TypeInfo
argument should exist for the life type of the type.
Therefore use type_register() when registering the list of CPU subtypes.

No functional change with the current implementation.

Cf. 918fd0839e for arm.

bc5b2da32b target-m68k: Detect attempt to instantiate non-CPU type in cpu_init()
Consolidate model checking into a new m68k_cpu_class_by_name().

If the name matches an existing type, also check whether that type is
(a sub-type of) TYPE_M68K_CPU.

This fixes, e.g., -cpu ide-hd asserting.

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().
