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.

Pass PowerPCCPU to kvmppc_handle_halt().

cpu: Pass CPUState to cpu_interrupt()

Move it to qom/cpu.h to avoid issues with include order.

Change pc_acpi_smi_interrupt() opaque to X86CPU.

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...

PPC: Bring EPR support closer to reality

We already used to support the external proxy facility of FSL MPICs,
but only implemented it halfway correctly.

This patch adds support for

  • dynamic enablement of the EPR facility
  • interrupt acknowledgement only when the interrupt is delivered...

ppc/booke: fix crit/mcheck/debug exceptions

Book E does not play games with certain bits of xSRR1 being MSR save
bits and others being error status. xSRR1 is the old MSR, period.
This was causing things like MSR[CE] to be lost, even in the saved
version, as soon as you take an exception....

PPC: Add support for MSR_CM

The BookE variant of MSR_SF is MSR_CM. Implement everything it takes in TCG to
support running 64bit code with MSR_CM set.

ppc: Move load and store helpers, switch to AREG0 free mode

Add an explicit CPUPPCState parameter instead of relying on AREG0
and rename op_helper.c (which only contains load and store helpers)
to mem_helper.c. Remove AREG0 swapping in
tlb_fill().

Switch to AREG0 free mode. Use cpu_ld{l,uw}_code in translation...
