A transition from CPUFooState to FooCPU can be considered safe,
just like FooCPU::env access in the opposite direction.
The only benefit of the FOO_CPU() casts would be protection against
bogus CPUFooState pointers, but then surrounding code would likely
break, too.
This should slightly improve interrupt etc. performance when going from
CPUFooState to FooCPU.
For any additional CPU() casts see 3556c233d931ad5ffa46a35cb25cfc057732ebb8
(qom: allow turning cast debugging off).

Make cpustats monitor command available unconditionally.

arguments to CPUState.

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.

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.

Embed CPUXtensaState as first member of XtensaCPU.
Let CPUClass::reset() call cpu_state_reset() for now.
