Microblaze: Convert Microblaze-pic handling to GPIOs
This patch uses inbound GPIO lines (IRQ and FIR) forinterrupts instead of using the old pic_cpu method,which doesn't correspond to real hardware.
This creates the CPU's inbound IRQ and FIR GPIO lines and...
microblaze: At swx, check that the reserved word is unmodified
This improves the reservation check for system emulation, makingit possible to catch stores that modify reserved word.

cpu: Introduce CPUClass::synchronize_from_tb() for cpu_pc_from_tb()
Where no extra implementation is needed, fall back to CPUClass::set_pc().

linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-user
The functions cpu_clone_regs() and cpu_set_tls() are not purely CPUrelated -- they are specific to the TLS ABI for a a particular OS.Move them into the linux-user/ tree where they belong....
cpu: Turn cpu_unassigned_access() into a CPUState hook
Use it for all targets, but be careful not to pass invalid CPUState.cpu_single_env can be NULL, e.g. on Xen.

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 beforebreakpoints.
Pass PowerPCCPU to kvmppc_handle_halt().
cpu: Replace do_interrupt() by CPUClass::do_interrupt method
This removes a global per-target function and thus takes us one stepcloser to compiling multiple targets into one executable.
It will also allow to override the interrupt handling for certain CPU...
target-microblaze: Move TCG initialization to MicroBlazeCPU initfn
Split off TCG initialization from cpu_mb_init() into mb_tcg_init() tocall it from the initfn.
Ensures that a QOM-created MicroBlazeCPU is usable.
target-microblaze: Mark as unmigratable
cpu_{save,load} were no-ops, so de facto it is unmigratable and nobackwards compatibility to keep. Therefore mark the MicroBlazeCPU asunmigratable at device level the QOM way and suppress "cpu_common" VMState registration by dropping CPU_SAVE_VERSION....
