Hi,

This series implements 3 Spectre related PowerPC features that
were added back in QEMU 2.12:

- CFPC: Cache Flush on Privilege Change
- SBBC: Speculation Barrier Bounds Checking
- IBS:  Indirect Branch Speculation

These options aren't much of a problem for users using latest
hardware and guests with recent Linux kernels. Users with outdated
hardware/firmware or trying to run AIX guests/guests with older
kernels, however, will need to fine tune these options because
QEMU defaults won't work.

Instead of making users rely on <qemu:commandline> elements to
hardcode the options in the XML, let's support them in Libvirt.
