Alexander Graf d3e35a1fe4 target-arm: A64: add stubs for a64 specific helpers
We will need helpers that only make sense with AArch64. Add
helper-a64.{c,h} files as stubs that we can fill with these
helpers in the following patches.

Mian M. Hamayun 26861c7ce0 target-arm: Add minimal KVM AArch64 support
Add the bare minimum set of functions needed for control of an
AArch64 KVM vcpu:
 * CPU initialization
 * minimal get/put register functions which only handle the
   basic state of the CPU

[PMM: significantly overhauled; most notably:
 * code lives in kvm64.c rather than using #ifdefs
 * support '-cpu host' rather than implicitly using whatever the
   host's CPU is regardless of what the user requests
 * fix bug attempting to get/set nonexistent X[31]
 * fix bug writing 64 bit kernel pstate into uint32_t env field

Peter Maydell b197ebd410 target-arm/kvm: Split 32 bit only code into its own file
Split ARM KVM support code which is 32 bit specific out into its
own file, which we only compile on 32 bit hosts. This will give
us a place to add the 64 bit support code without adding lots of
ifdefs to kvm.c.

Alexander Graf 96c04212ba target-arm: Add AArch64 gdbstub support
We want to be able to debug AArch64 guests. So let's add the respective gdb
stub functions and xml descriptions that allow us to do so.

Alexander Graf 14ade10f84 target-arm: Add AArch64 translation stub
We should translate AArch64 mode separately from AArch32 mode. In AArch64 mode,
registers look vastly different, instruction encoding is completely different,
basically the system turns into a different machine.

So let's do a simple if() in translate.c to decide whether we can handle the
current code in the legacy AArch32 code or in the new AArch64 code.

So far, the translation always complains about unallocated instructions. There
is no emulator functionality in this patch!

[PMM:
 * provide no-op versions of a64 functions ifndef TARGET_AARCH64;
   this lets us avoid #ifdefs in translate.c
 * insert the missing call to disas_a64_insn()
 * stash the insn in the DisasContext rather than reloading it in
   real_unallocated_encoding()
