These two simple patches make qemu correctly UNDEF where required in the
Neon load/store space. We also catch and UNDEF on an UNPREDICTABLE rather
than indexing off the end of the register file.
Tested in the usual way with random instruction sequences.

With softfloat it's not possible to play with the overflow of an
unsigned value to get the 0 case partially correct. Use a special case
for that. Using a division to generate an infinity is the easiest way
that works for both softfloat and softfloat-native.

Hi Alex,
Here are several more minor tweaks/improvements to the pseries machine
emulation.
Currently, the qemu emulated pseries machine puts
"qemu,emulated-pSeries-LPAR" in the device tree's root level 'model'
property. Unfortunately this confuses some installers and ybin, which
expect this to start with "IBM" on pSeries machines. This patch addresses
this problem, making the property
Currently the qemu pseries machine numbers its virtual serial devices
from 0. However, existing pSeries machines running pHyp number them from
0x3000.
In theory these indices are arbitrary, since everything necessary for the
kernel to find them is advertised in the device tree. However the d

The original pSeries machine was limited to 32 CPUs, more or less
arbitrarily. Particularly when we get SMT KVM guests it will be
pretty easy to exceed this. Therefore, raise the max number of CPUs
in a pseries machine guest to 256.
