Andreas Färber 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.

Andreas Färber 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.

Andreas Färber bd1b282836 target-alpha: Update AlphaCPU to QOM realizefn
Update the alpha_cpu_realize() signature and hook up to
DeviceClass::realize. Set realized = true in cpu_alpha_init().

qapi/error.h is included through qdev now and no longer needed.

Andreas Färber 0e44a02301 target-alpha: Detect attempt to instantiate non-CPU type in cpu_init()
Check in alpha_cpu_class_by_name() whether the type found is actually
(a sub-type of) TYPE_ALPHA_CPU.

This fixes, e.g., -cpu typhoon-pcihost asserting.

Andreas Färber 2b8c275499 cpu: Add model resolution support to CPUClass
Introduce CPUClass::class_by_name and add a default implementation.
Hook up the alpha and ppc implementations.

Introduce a wrapper function cpu_class_by_name().

Andreas Färber 75a192aa68 qemu-common.h: Make qemu_init_vcpu() stub static inline
Turn the *-user macro into a no-op inline function to avoid
unused-variable warnings and band-aiding #ifdef'ery.

This allows to drop an #ifdef for alpha and avoids more for unicore32
and other upcoming trivial realizefn implementations.
