Subject: [PATCH 0/2] KVM: x86: emulate fxsave and fxrstor

[1/2] adds the emulation (and could be split into two patches if you'd like),
[2/2] just refactors the code.

This should fix an issue that users are hitting.  Laszlo found several reports:
 - https://bugs.launchpad.net/qemu/+bug/1623276
 - https://bugzilla.proxmox.com/show_bug.cgi?id=1182
 - https://bugs.archlinux.org/task/50778

I have only tested it with a simple kvm-unit-tests, though.  Reproducing the
iPXE issue is on the way ...
