  accel: Remove unused AccelClass::opt_name attribute
  numa: improve cpu hotplug error message with a wrong node-id
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

The AccelType type was converted to AccelClass QOM
object on b14a0b74, and the original data type had
a field to store the option name which in turn was
used to search an accelerator. The lookup method
(accel_find) changed too, making the option field
unnecessary but it became AccelClass::opt_name despite
that. Therefore, and given that none accelerator
implementation sets AccelClass::opt_name, let's
remove this attribute.

On pseries, core-ids are strongly binded to a node-id by the command
line option. If an user tries to add a CPU to the wrong node, he has
an error but it is not really helpful:

  qemu-system-ppc64 ... -smp 1,maxcpus=64,cores=1,threads=1,sockets=1 \
                        -numa node,nodeid=0 -numa node,nodeid=1 ...

  (qemu) device_add power9_v2.0-spapr-cpu-core,core-id=30,node-id=1
  Error: node-id=1 must match numa node specified with -numa option

This patch improves this error message by giving to the user the good
node-id to use with the core-id he's providing

to the QEMU CPU model, so it is enabled as default.
Also:

- Fix the alignment of vector registers (and change the data type)
- Properly generate ELF_HWCAP for s390x for linux-user
- Use a gvec helper for VECTOR SELECT
