target-openrisc: Clean up double QOM casts

Instead of calling openrisc_env_get_cpu(), casting to CPU() via the
ENV_GET_CPU() compatibility macro and casting back to OPENRISC_CPU(),
just call openrisc_env_get_cpu() directly.

kvm: Pass CPUState to kvm_on_sigbus_vcpu()

Since commit 20d695a9254c1b086a456d3b79a3c311236643ba (kvm: Pass
CPUState to kvm_arch_*) CPUArchState is no longer needed.

Allows to change qemu_kvm_eat_signals() argument as well.

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.

target-i386: Drop version 5 CPU VMState support

Version 5 contained the halted field, that we are about to move from
CPUX86State to CPUState. To avoid inventing new VMSTATE macros for
calculating a negative offset from CPUX86State to the field in CPUState,
rather bump the minimum version from 3 to 6. We're at 12 currently.

cpu: Move halted and interrupt_request fields to CPUState

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.
