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.

Expose vmstate_cpu as vmstate_x86_cpu and hook it up to CPUClass::vmsd.
Adapt opaques and VMState fields to X86CPU. Drop cpu_{save,load}().

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.

Adapt the signature of x86_cpu_realize(), hook up to
DeviceClass::realize and set realized = true in cpu_x86_init().
The QOM realizefn cannot depend on errp being non-NULL as in
cpu_x86_init(), so use a local Error to preserve error handling behavior
on APIC initialization errors.

[AF: Invoke parent's realizefn]

Commit de024815e3 (target-i386: QOM'ify
CPU init) moved mce_init() call from helper.c:cpu_x86_init() into
X86CPU's cpu.c:x86_cpu_initfn().
mce_init() checks for a family >= 6 though, so we could end up with a
sequence such as for -cpu somecpu,family=6:
x86_cpu_initfn => X86CPU::family == 5
mce_init => no-op
cpu_x86_register => X86CPU::family = 6
=> MCE unexpectedly not init'ed
or for -cpu someothercpu,family=5:
x86_cpu_initfn => X86CPU::family == 6
mce_init => init'ed
cpu_x86_register => X86CPU::family = 5
=> MCE unexpectedly init'ed
Therefore partially revert the above commit. To avoid moving
mce_init() back into helper.c, foresightedly move it into a
new x86_cpu_realize() function and, in lack of ObjectClass::realize,
call it directly from cpu_x86_init().
While at it, move the qemu_init_vcpu() call that used to follow
mce_init() in cpu_x86_init() into the new realizefn as well.

Embed CPUX86State as first member of X86CPU.
Distinguish between "x86_64-cpu" and "i386-cpu".
Drop cpu_x86_close() in favor of calling object_delete() directly.
For now let CPUClass::reset() call cpu_state_reset().
