Instead of loading kernels, device trees, and the like to
the system address space, use the CPU's address space. This
is important if we're trying to load the file to memory or
via an alias memory region that is provided by an SoC
object and thus not mapped into the system address space.

Allow the translate subroutines to return false for invalid insns.
At present we can of course invoke an invalid insn exception from within
the translate subroutine, but in the short term this consolidates code.
In the long term it would allow the decodetree language to support
overlapping patterns for ISA extensions.

In our Armv8a server, we try to configure the vhost scsi but fail
to boot up the guest (-machine virt-2.10). The guest's boot failure
is very early, even earlier than grub.
There are 3 virtqueues (ctrl, event and cmd) for virtio scsi device,
but ovmf and seabios will only set the physical address for the 3rd
one (cmd). Then in vhost_virtqueue_start(), virtio_queue_get_desc_addr
will be 0 for ctrl and event vq when qemu negotiates with ovmf. So
vhost_memory_map fails with ENOMEM.
This patch just fixs it by early quitting the virtqueue start/stop
when virtio_queue_get_desc_addr is 0.
Btw, after guest kernel starts, all the 3 queues will be initialized
and set address correctly.
Already tested on Arm64 and X86_64 qemu.

Let's also put the 31-bit hack in front of the REAL MMU, otherwise right
now we get errors when loading a PSW where the highest bit is set (e.g.
via s390-netboot.img). The highest bit is not masked away, therefore we
inject addressing exceptions into the guest.
The proper fix will later be to do all address wrapping before accessing
the MMU - so we won't get any "wrong" entries in there (which makes
flushing also easier). But that will require more work (wrapping in
load_psw, wrapping when incrementing the PC, wrapping every memory
access).
This fixes the tests/pxe-test test.
