This code moves FPU handling from the non-preemptible part of running
a VCPU, way further out into the KVM_RUN ioctl handling. That way there
is no need to continuously save and load the qemu FPU user context
every time a VCPU context switches, or goes to sleep in the host kernel.

v2:
- move FPU switching out to kvm_arch_vcpu_ioctl_run (David Hildenbrand)
- remove fpu handling from arch/x86/kvm/emulator.c (no longer needed)
