While GDB can work with any XML description given to it there is
special handling for SVE registers on the GDB side which makes the
users life a little better. The changes aren't that major and all the
registers save the $vg reported the same. All that changes is:
- report org.gnu.gdb.aarch64.sve
- use gdb nomenclature for names and types
- minor re-ordering of the types to match reference
- re-enable ieee_half (as we know gdb supports it now)
- $vg is now a 64 bit int
- check $vN and $zN aliasing in test

This test seems flaky and reports attachment even when we failed to
negotiate the architecture. However the fetching of the guest
architecture will fail tripping up the gdb AttributeError which will
trigger our early no error status exit from the test

It seems older and non-multiarach aware GDBs might not fail gracefully
when faced with something they don't know. For example when faced with
a target XML for s390x the Ubuntu 18.04 gdb will generate an internal
fault and prompt for a core dump.
Work around this by invoking GDB in a more batch orientated way and
then trying to filter out between test failures and gdb failures.

This test exercises the gdbstub while runing the sve-iotcl test. I
haven't plubmed it into make system as we need a way of verifying if
gdb has the right support for SVE.

A very simple test case which sets and reads SVE registers while
running a test case. We don't really need to compile a SVE binary for
this case but we will later so keep it simple for now.
